LG OLED C6 (WOLED) vs Sony BRAVIA 7 II

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 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode for watching, Professional, we measured about 2,000 nits of peak brightness, so the panel’s capabilities are truly large. Of course, in Mini-LED sets a test-pattern result is only part of the story, because much still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform really well. Depending on the scene, the brightness we measured in films ranged from about 1,100 to as much as 1,700 nits. That’s a level at which HDR has proper punch and bright highlights can be genuinely impressive. It’s not perfect in every situation. With small bright elements on a very dark background, the Bravia 7 II clearly prioritises maintaining good black levels, so their brightness can fall to around 500 nits. It still looks good, but it’s clear the TV doesn’t always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is where True RGB was meant to deliver one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured roughly 98% DCI-P3 coverage and 88% BT.2020, so the potential for showing highly saturated colours is substantial. In RGB TVs the matter is a bit more complex. When we repeated the same measurements with a film-like background applied, gamut coverage dropped to about 92% DCI-P3 and 78% BT.2020. Those are still good numbers, especially for an RGB Mini-LED TV, but they show that the final result largely depends on how the algorithms drive the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain strong saturation. The biggest differences are visible in blue shades, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primaries. True RGB therefore offers genuinely greater potential, but, as with brightness, a lot depends on what’s actually happening on screen.

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.

To evaluate the factory colours we chose the Professional mode, because it performs best among the available presets. It's not perfect. In SDR the white balance is slightly biased toward magenta, so some scenes look a little warmer and less neutral than they should. A bigger issue is the gamma, which sits closer to 2.5 than 2.4. As a result the image is a bit too dark in places, especially in the mid-tones. In HDR the situation is better. As brightness increases there's a little too much red, but it isn't something that really jumps out while watching. Overall the Professional mode is a good starting point, though you can get a bit more out of it with calibration.

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.

After calibration the Bravia 7 II can look significantly better. First and foremost, we managed to set the white balance very well in both SDR and HDR. Gamma can also be improved, and after correction it runs very close to the reference value. For most users those changes will have the biggest impact on the picture. There is, however, a limitation with the colours themselves. On the Bravia 7 II Sony does not provide access to a traditional CMS that would let us adjust individual hues separately. Much is left to the algorithms controlling the True RGB backlight. If the TV reproduces a specific colour inaccurately, we are not always able to do anything about it. In our measurements this is most apparent in parts of the reds and blues, where errors can still be quite large. That does not, however, undermine the value of calibration. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference from the factory settings is noticeable.

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.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of Sony's biggest advantages over the competition. Sony has for years excelled at digital image processing, and it's clear here too. Above all, the 'Smooth Gradation' function works very well, smoothing weaker tonal transitions in poorer-quality content. The safest setting is low, but we'd comfortably recommend medium as well. The effect is stronger, and the TV still handles fine detail very delicately. Some minor details may be slightly smoothed, but Sony does it much more subtly than many other brands. Upscaling is also very good. Lower-resolution content is nicely upscaled to 4K; the image looks clean and retains a lot of detail. Of course the TV won't magically turn native HD into true 4K, but the Bravia 7 II does very well with what can be pulled from such a source.

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.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you'd expect from a TV of this class. With sport or games at 120 fps the picture is suitably smooth, and for films Sony provides an advanced motion interpolation system. You can therefore adjust the level of interpolation separately and choose whether to retain a more cinematic motion or achieve noticeably greater smoothness. Motion blur itself is a bit worse. The VA panel used isn't among the fastest, and moving objects can show a slight trailing, especially against darker backgrounds. It's not at a level that will seriously disturb normal viewing, but last year's Bravia 7 was better in this regard and had a noticeably faster panel.

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.

Bravia 7 II has pretty much everything you'd want from a good console TV today. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to low-latency mode. HGiG works correctly, so once you configure HDR on the console the TV won't try to brighten the image on its own. Just remember to turn off tone mapping in the TV's menu. Another plus is Dolby Vision in game mode, which will be especially useful for Xbox owners. Sony also includes its own Game Menu, where you can quickly view key signal info, check VRR or change gaming settings without digging through the full TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz. Our biggest complaint is not really about the features but the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 with 48 Gbps bandwidth. One of those is also the eARC port. So if you connect a soundbar or AV receiver via HDMI, in practice you only have one full HDMI 2.1 left for a console or PC. With a single console that's fine, but with a PS5, an Xbox and an audio setup it starts to feel cramped. That's hard to justify from Sony. In cheaper TVs two HDMI 2.1 ports can still be accepted, but in a model of this class, especially in 2026, we'd expect all four ports to be HDMI 2.1.
