Sony BRAVIA 5 (XR5) vs LG OLED C6 (WOLED)

Looking at similar results in terms of blackness and contrast, we expected equally stable performance as last year's model when it came to HDR content. Unfortunately – and this needs to be said outright – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 is impressive: in our synthetic tests, the television achieved around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all film scenes. When small, point-like elements appear on the screen, something that had usually been polished with surgical precision in Sony's case is this time noticeably lacking. The algorithms attempt to maintain deep black around small objects, but the side effect is that details can be dimmed to such an extent that they become barely visible. Just consider the example of the film Sicario 2 – in some scenes there, small light sources practically disappeared, as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with more light, the Bravia 5 shows that it can shine: literally and figuratively. Then the television achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during film screenings. The impression is really positive; the brightness adds dynamism, and the colours appear vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because evidently something has gone in a direction it shouldn’t have. Technological progress – more zones, greater backlighting power – has not been supported by the well-crafted image management that we usually associate with Sony. Fortunately, there are elements that have not been worsened and are, in fact, at a very high level. We are talking about colour reproduction. Thanks to the application of the PFS filter, the colour palette coverage is excellent – around 97% DCI-P3 and 75% BT.2020. These are values that allow for truly broad colour reproduction, giving films a sense of naturalness and cinematic quality.

The HDR performance of the LG C6 is really very good. LG Display's new WOLED panel has primarily brought a considerable increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can deliver similar values in many typical film scenes. That gives the HDR the necessary impact. Bright highlights, lamps and sunlight can be really intense, and most HDR films simply look very impressive. Of course it's still an OLED, so brightness falls in scenes with a lot of white. This is well illustrated by the fifth scene in the film The Meg, where the C6 reached around 600 to 700 nits. That's still a very good result, but it also shows that the new panel hasn't shed all the limitations typical of OLEDs.

Colours

When it comes to colours, there is also little to complain about. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice the colours are very saturated and, importantly, stable across different scenes. This is worth emphasising, because not every TV behaves the same in this respect. In some RGB Mini LED models colour saturation can depend more strongly on image brightness. A wider colour palette is nowadays offered mainly by QD-OLED TVs and new SQD models with a new generation of quantum dots. However, the C6 still performs very strongly here and is able to produce suitably saturated colours in most film scenes.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it provides the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a showroom display than for a living room. However, the Cinema mode alone does not mean we can always expect cinematic picture quality. With SDR content, we had virtually no major complaints – the slightly warmed white balance gave the scenes a somewhat golden tone, but it was nothing that was visually jarring. However, the problem arose with HDR material. Here, the colour reproduction simply looked poor. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store's "super vibrant image" mode, where everything is overexposed and artificially boosted.

This situation also made brightness management seem overly aggressive. The EOTF graph clearly showed that the television had problems with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was difficult to remain indifferent here – thus we quickly decided to go for calibration.

Right out of the box the LG C6 is pretty well set up, especially if you choose Filmmaker mode. In SDR material the white balance is decent, although as brightness increases it starts to lack a bit of red. The picture becomes a little cooler as a result, but it’s not such a big difference that it stands out during normal viewing. More happens in the brightness response itself. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 over much of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses some depth compared with how it should look in a dark room. In HDR the situation is a bit more interesting. The start of the grayscale looks very good, but from about 20–30% brightness the white balance starts to drift more and more. As brightness rises there’s more red and a noticeable lack of blue. In the brightest highlights the difference is already significant and also affects reproduction of some colors. The EOTF curve itself is handled fairly well over most of the range. The C6 only has a tendency to slightly brighten the image, which we also saw during our film comparisons. The largest deviation appears around the brightest highlights, where the TV begins to adapt the signal to the panel’s capabilities. So the out-of-the-box Filmmaker mode in HDR isn’t perfect, but overall it performs well. The biggest room for improvement is the white balance, especially at high brightness.

After calibration, the situation changed dramatically. We managed to adjust the white balance so that entire scenes began to look more natural, and the image gained cohesion and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously marred some shots. Suddenly, it turned out that the Bravia 5 can extract significantly more from films than the “out of the box” impression suggested. Indeed, if we look at the graphs and compare them with the patterns, we can see that the beginning of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as it is a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritise the visibility of details – and in practice, it's hard to disagree with that. We would rather see the texture of the material on the screen than a pitch-black blob where all nuances are lost.

The calibration itself was truly beneficial. After about an hour spent on the settings, we felt that the image resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we like Sony televisions: because when we fine-tune them, they can reward us with an image that captivates for long hours.

LG TVs have been very receptive to calibration for years and the C6 is no exception. After adjustment the white balance was set almost perfectly, and most colour errors dropped to values below 3, often even around 2. In practice this means very accurate colour reproduction, both in SDR and HDR. An interesting quirk only appeared with the luminance response in HDR. On a standard EOTF chart everything looks almost ideal and at first glance it would be hard to criticise. Only when we measured the TV's behaviour with filters based on actual film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

This is not a huge difference and many people may even view it positively, because HDR consequently looks a little more striking. From the perspective of fidelity to the source material this is not ideal, however, as some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is rather unusual for LG. In previous generations the brand's TVs typically stuck very closely to the reference picture characteristic after calibration. With the C6 we are still very close to the standard, but this subtle brightness boost is indeed noticeable in films and TV series.

Bravia 5 carries within it the genes of Sony, which have remained untouched – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. It is no coincidence that for years it has been believed that it is televisions of this brand that set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films or YouTube in lower resolutions, here they get equipment that can transform such content into an unexpectedly pleasant experience. On board, we find several tools worth activating. The first of these is "digital noise reduction". Set to a medium level, it works perfectly – smoothing tonal transitions, which usually cause the most trouble in low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, meaning the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image displayed after scaling is soft, yet at the same time sharp and clear. The contours of characters are clearly visible, while backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower quality materials – Bravia 5 only confirms why Sony is regarded as a benchmark in this field.

Here the LG C6 has taken a real step forward. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That's a considerable plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function in particular works very well. With heavily compressed material it can effectively hide ugly banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it set to "Low". That way the improvement is clear and the TV does not yet start blurring fine details. Higher settings smooth the image more aggressively but can already remove some of the natural texture of objects on the screen. Upscaling itself also performs very well. Lower-resolution content is sharpened correctly, edges look clean, and the processor quite effectively reconstructs fine details. In this respect the C6 is already very close to LG's best TVs and the differences compared with the G6 are small.

Bravia 5 received a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary smoothness technology – comes into play. Thanks to it, we can adjust the character of the image to our own preferences. The "smoothness" slider allows you to transition from a cinematic feel with a slight "jitter" of the film frame to a nearly theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more cinematic and natural it feels. In the options, we will also find an additional setting that Sony has called "clarity". This is nothing more than the BFI function (i.e., inserting black frames), which is meant to improve motion sharpness. It sounds great in theory, but in practice, one must use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. Therefore, if we wish to use it, we recommend the lowest possible level – "1" out of the available ten. This way, we gain a bit better motion clarity without risking a loss of half the image brightness.

LG C6 received a panel with a maximum refresh rate of 165 Hz, which is great news above all for gamers using a powerful PC. In films, sport or on consoles we will of course make use of up to 120 Hz, but even then it is hard to fault the motion clarity. As befits an OLED, the panel's response time is almost instantaneous. Moving objects therefore do not leave the characteristic smearing or trails that we can still see on LCD televisions. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.

For films and television LG has also prepared the TruMotion motion smoothing system. In the user settings you will find two separate sliders. De-Judder primarily addresses low frame-rate content, that is mainly films and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or set a higher value if you want a very smooth image. De-Blur is useful for higher frame-rate material, chiefly sports broadcasts and 50/60 fps television.

In the Bravia 5, there is a significant improvement compared to the X90L model from two years ago. The television offers literally everything its predecessor had, but this time the issues that could frustrate gamers have been fixed. The problems with setting variable refresh rate (VRR) have disappeared, and there are no longer any issues with configuring HDR content in HGiG mode. In short: we get hardware that simply works as it should, without any fuss. Therefore, the Bravia 5 has everything you could expect from a modern gaming television – and it can be reasonably advertised with the slogan “ready for PS5.” This is a statement we couldn't make about the X90L model. Well done, Sony!

It’s just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be a problem for most people, but if someone has a console, soundbar, and additional equipment hooked up via HDMI, at some point there will be a need to choose or juggle the cables.

LG has long focused heavily on gamers, and the C6 really lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can run at up to 165 Hz. There is also VRR from 40 to 165 Hz, ALLM and a properly working HGiG. A big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up Game Mode. It's rounded off by a Game Bar, from which you can quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is therefore one of those TVs that is really hard to fault. Whether you're gaming on a PlayStation, an Xbox or a PC, practically everything you could expect from a modern gaming TV is available here.
