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

Looking at similar results in terms of black levels and contrast, we expected the same stable performance as last year's model when it comes to HDR content. Unfortunately – and this must be said plainly – there has been a regression here that is hard to miss. The paradox is that the peak brightness of the Bravia 5 can be impressive: in our synthetic tests, the TV reached around 1000 nits in HDR. Sounds great, right? The problem is that this power doesn't always have a real impact on all movie scenes. When small, pinpoint elements appear on the screen, something that in Sony's case was usually fine-tuned with surgical precision, this time it clearly falters. The algorithms try to maintain deep blacks around small objects, but the side effect is that details can be dimmed to the point of becoming barely visible. One only needs to bring up the example of the movie Sicario 2 – there, in some scenes, small light sources practically vanished 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. At those times, the TV achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during movie screenings. The impression is really positive; the brightness adds dynamism, and the colours look vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because it is evident that something has gone in the wrong direction. Technological progress – more zones, more backlight power – has not been supported by the kind of refined image management that we usually associate with Sony. Fortunately, there are elements that have not been compromised and are actually at a very high level. We are talking about colour reproduction. Thanks to the use of the PFS filter, the colour palette coverage is excellent – about 97% DCI-P3 and 75% BT.2020. These values allow for a truly wide colour reproduction, giving films a natural and cinematic character.

The HDR performance of the LG C6 is really very good. LG Display’s new WOLED panel has mainly brought a significant increase in brightness. In our unit we measured around 1500 nits and, importantly, the TV can show similar values in many normal movie scenes as well. That gives HDR real punch. Bright highlights, lamps and sunlight can be genuinely intense, and most HDR movies simply look very impressive. Of course it’s still an OLED, so brightness falls in scenes with a lot of white. The fifth scene from the movie The Meg illustrates this well, where the C6 reached around 600 to 700 nits. That’s still a very good result, but it also shows the new panel hasn’t shed all the limitations typical of OLEDs.

Colours

When it comes to colours, it’s also hard to raise major objections. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice colours are very saturated and, importantly, stable regardless of the scene. That’s 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 gamut today is mainly offered 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 movie scenes.

Sony Bravia 5 was obviously tested in the best possible mode, which is the Movie mode. Right out of the box, it delivers the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a store display than a living room. However, the Movie mode alone does not guarantee that we can always expect cinematic picture quality. In SDR content, we had no significant complaints – the slightly warmed white balance gave the scenes a golden hue, but it was nothing that was glaring. However, a problem arose with HDR materials. Here, the colour reproduction simply looked bad. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store mode of "super vivid picture," where everything is blown out and artificially boosted.

This situation made brightness management seem too aggressive as well. The EOTF graph clearly showed that the television has trouble with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was hard to remain indifferent here – that’s why we quickly decided to go for calibration.

Right out of the box the LG C6 is quite well set up, especially if you choose the Filmmaker mode. In SDR material the white balance is decent, although as brightness increases there is a slight lack of red. The image becomes a bit cooler, but not enough for it to be very noticeable during normal viewing. More is happening in the brightness characteristic. Gamma is a little low and instead of holding at 2.4, for a large part of the range it sits closer to 2.1–2.2. 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 darkened room.

In HDR the situation is a bit more interesting. The start of the greyscale looks very good, but from about 20–30% brightness the white balance starts to drift increasingly. As brightness rises there is more red and a noticeable lack of blue. In the brightest sections the difference is already significant and also affects the reproduction of some colours. The EOTF curve itself is followed quite well through most of the range. The C6 only tends to slightly brighten the image, which we also saw in our film comparisons. The largest deviation appears around the brightest parts, where the TV starts adapting the signal to the panel's capabilities.

The factory Filmmaker setting in HDR is therefore not perfect, but overall performs well. The biggest area for improvement is the white balance, especially at high brightness.

After calibration, the situation changed dramatically. We managed to tune the white balance so that entire scenes began to look more natural, and the image gained coherence and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously spoiled some shots. Suddenly, it turned out that the Bravia 5 can extract much more from films than the first contact "straight out of the box" suggested. Indeed, if we look at the graphs and compare them with the standards, we can see that the beginning of the EOTF curve slightly strays beyond the reference line. However, this is not so much a calibration error as it is a natural limitation of the Mini-LED technology that cannot be bypassed. Sony, rather than clinging tightly to perfect black, prefers to prioritise the visibility of details – and in practice, it’s hard to disagree with that. We prefer to see the texture of the material on the screen rather than a pitch-black spot where all nuances disappear.

The calibration itself was really beneficial. After about an hour spent on settings, we felt that the image resembled that of 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 love Sony televisions: because once we fine-tune them, they reward us with a picture that captivates for long hours.

LG TVs have long responded very well to calibration, and the C6 is no exception. After adjustments we managed to set the white balance practically perfectly, and most colour errors fell below 3, often down to around 2. In practice this means very accurate colour reproduction in both SDR and HDR. An interesting detail only appeared with the HDR brightness response. On a classic EOTF chart everything looks almost perfect and at first glance it would be hard to find fault. Only when we measured the TV’s behaviour using filters based on real film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

It’s not a huge difference and many viewers may even see it as a positive, because HDR looks a bit more striking as a result. From the point of view of fidelity to the source material, however, it’s not ideal — 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 held very closely to the reference picture curve after calibration. The C6 is still very close to the standard, but that subtle brightness 'boost' can indeed be noticed in films and TV series.

Bravia 5 carries the genes of Sony, which remain intact – and thank goodness for that, because we're talking about absolutely exceptional digital image processing. It's no coincidence that for years, it's been considered that TVs from this brand 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 turn such content into a surprisingly enjoyable experience. On board, we find several tools worth activating. The first of these is "digital noise reduction." Set to a medium level, it works superbly – smoothing out tonal transitions that usually cause the most trouble in low-quality materials while introducing no artificial artifacts. Importantly, it also doesn't remove the cinematic character, which is 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 presented after scaling is soft, yet sharp and clear. The outlines of characters are well-defined, and backgrounds maintain their texture without excessive artificial sharpening. It's hard to find a better TV for watching lower quality materials – Bravia 5 only confirms why Sony is considered the benchmark in this area.

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

Bravia 5 has 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 motion smoother – comes into play. Thanks to this feature, we can adjust the character of the picture to our own preferences. The "smoothness" slider allows us to transition from a cinematic feel with a slight "judder" to a 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 film-like and natural it becomes. In the options, we also find an additional setting that Sony calls "clarity". This is nothing more than the BFI function (which inserts black frames) aimed at improving motion sharpness. It sounds great in theory, but in practice, it must be used with caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. So if we want to use it, we recommend setting it to the lowest level – "1" out of the available ten. That way, we gain a bit better motion sharpness without risking losing half the brightness of the picture.

The LG C6 features a panel with a maximum refresh rate of 165 Hz, which is great news especially for gamers using a powerful PC. For movies, sport and consoles we’ll of course be limited to 120 Hz at most, but even then it’s hard to fault the motion clarity. As you’d expect from an OLED, the panel’s response time is near-instant. Moving objects therefore don’t leave the characteristic smearing you still see on LCD TVs. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.

For movies and TV, LG has also included a motion smoothing system called TruMotion. In the user settings you’ll find two separate sliders. De-Judder is primarily for low-frame-rate material, namely movies and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or increase it if you prefer a much smoother picture. De-Blur, on the other hand, is useful for higher-frame-rate content, mainly sports broadcasts and 50/60 fps TV.

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 addressed. Problems with setting the variable refresh rate (VRR) have disappeared, and there are no longer issues with configuring HDR content in HGiG mode. In short: we get a device that simply works as it should, without any hassles. So, the Bravia 5 has everything you can expect from a modern gaming TV – and it can be confidently advertised with the slogan "ready for PS5." That's something we couldn't say 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 an issue for most people, but if someone has a console, soundbar, and additional equipment connected via HDMI, at some point they'll have to choose or juggle cables.

LG has long focused heavily on gamers, and the C6 essentially lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can even run at 165 Hz. On top of that there’s VRR from 40 to 165 Hz, ALLM and a properly functioning HGiG. Another big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up game mode. The package is rounded out by the Game Bar, which lets you quickly check key signal parameters and change settings without leaving your game. In terms of features alone, the C6 is one of those TVs it’s really hard to fault. Whether you play on PlayStation, Xbox or PC, practically everything you could expect from a modern gaming TV is available here.
