SONY Bravia 9 II XR95M2 vs LG OLED C6 (WOLED)

The real showcase of the new backlight architecture and Sony’s processor is the reproduction of HDR content. At the official launch engineers at Sony said (not officially 😉) that the Bravia 9 II’s brightness would be almost identical to the capabilities of their professional director’s monitor BVM-HX3110, which is priced at astronomical sums. Our lab tests confirmed these were not empty promises. During synthetic measurements on the L20 test pattern the TV easily exceeded the 4000 nits peak brightness barrier. More importantly, these remarkable results translate directly to real movie scenes. In most of the demanding shots we tested the screen easily maintained brightness around 2500–3000 nits. Regardless of the scene, whether the light was small and pinpoint or flooded nearly the entire screen, the HDR effect was incredibly intense.

Colors

Color is another key pillar of RGB Mini LED technology (True RGB as implemented by Sony). Specifically for testing these kinds of screens we added a permanent new testing section to see how TVs handle colors in real-world conditions. Traditional synthetic test patterns are no longer enough to confirm real color-gamut coverage. From now on we also measure color saturation directly in selected movie scenes by overlaying measurement points. So how do the colors perform?

In synthetic tests the Bravia 9 II posts excellent results. For the popular DCI-P3 color space for HDR the color-gamut coverage was almost 98%, while for the very wide, demanding BT.2020 space the instrument indicated nearly 90%. However, in real, varied scenes these values drop by a few percent. This is directly due to the nature of zone-based RGB backlighting. When differently colored elements or bright white highlights appear side by side, light from the zones starts to mix slightly, creating a white backlight. This of course affects color saturation, slightly reducing it. This shows that despite Sony’s brilliant RGB LED control algorithm, the number of zones is still too small to eliminate this effect entirely.

Is this a reason to complain? Of course not. The Bravia 9 II’s color coverage ultimately matches that of a very good QLED TV, and it’s important to remember: the vast majority of HDR movies and series are distributed in the DCI-P3 gamut. In that standard Sony easily maintains very high color saturation, regardless of the scene.

The HDR effect on the LG C6 is really very good. LG Display's new WOLED panel primarily brought a significant increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can show similar values in many normal movie scenes. That gives HDR the proper impact. Bright highlights, lamps, or sunlight can be really strong, and most HDR movies simply look very impressive. Of course it's still an OLED, so brightness drops in scenes with a lot of white. The fifth scene of The Meg illustrates this well, where the C6 reached about 600-700 nits. That's still a very good result, but it also shows the new panel hasn't removed all the limitations typical of OLEDs.

Colors

When it comes to color, 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 colors are very saturated and, importantly, stable regardless of the scene. That's worth emphasizing, because not every TV behaves the same in this respect. In some RGB Mini LED models color saturation can depend more strongly on image brightness. Today a wider color gamut 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 generate appropriately saturated colors in most movie scenes.

Contrary to appearances and high expectations, the Bravia 9 II we tested showed some issues with its factory tuning straight out of the box. Looking at the white balance charts, you can see it is not perfect. In SDR content the red component was primarily lacking, causing the picture to shift toward cooler, bluish tones. In HDR the white balance in this respect looked much better. So where do the visible errors in image reproduction come from? They result from unexpected tuning of the gamma and the EOTF curve. In both cases the Bravia 9 II straight from the factory showed a clear deviation from reference standards.

In SDR content the gamma was definitely too high; at its most extreme it hovered very close to 2.8 instead of the reference 2.4. In practice this meant the image was artificially darkened and appeared washed-out, with details in dark areas (shadows) completely disappearing. The opposite occurred with HDR material, where brightness reproduction is handled by the EOTF curve. That curve was pushed too far above the correct value, resulting in the image being artificially brightened across most luminance ranges. As with every TV we test, we subjected this unit to professional calibration. You can see the results and how we managed to correct these factory errors below.

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.

Fortunately, with professional calibration, most of the Bravia 9 II's factory missteps can be effectively eliminated. We were able to precisely correct, above all, the white balance and the gamma curve and EOTF. After these adjustments, in everyday use and during movie sessions the TV looks much better. The image gained proper depth, the cool tint in the whites disappeared, and shadow details that had previously been lost due to too-high gamma finally became clearly visible. Although we ultimately rate color accuracy as very good, as specialists we must point out one fairly serious design flaw in this model. The Bravia 9 II could look even better if not for the complete lack of an advanced color management system in the TV's menu.

While basic white balance correction can be performed here without issue, the settings lack options for adjusting specific colors. We tried to tackle this in every possible way: both the traditional method using the remote and via dedicated calibration software for Bravia TVs. Unfortunately, that function has been completely locked. We suspect this may stem from the specifics of the new RGB architecture, which imposes its own limitations. It's a real shame, because without it you can't refine color reproduction to perfection. The inaccurate red still stands out, for example. One can only hope Sony will fix this shortcoming over time with an update.

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 color errors dropped to values below 3, often even around 2. In practice this means very accurate color reproduction in both SDR and HDR. An interesting detail appeared only with the HDR brightness characteristic. On a classic EOTF chart everything looks nearly ideal, and at first glance it would be hard to find fault. Only when we measured the TV’s behavior using filters based on actual movie 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 people may even see it as a positive, because HDR looks a bit more impressive this way. From the standpoint of fidelity to the source material this isn’t ideal — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is somewhat unusual for LG. In previous generations, the brand’s TVs typically stuck very closely to the reference tone curve after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness is indeed noticeable in films and series.

Digital processing and upscaling have long been Sony’s signature strength, and after testing the Bravia 9 II we can confidently say nothing has changed on the market in that respect. Sony is still at the forefront. Their proprietary XR image processor, which in this model works with the main MediaTek Pentonic 1000 chip, deserves the highest praise. That combination delivers excellent results. The upscaling of lower-resolution content is extremely effective and precise.

However, what most deserves praise in the XR processor’s performance is the tonal transition smoothing feature. The system can reduce posterization in heavily compressed material to virtually zero. Crucially, the algorithm does this in a very intelligent way. It removes only the annoying digital "steps" in gradients without blurring fine texture details or creating an artificial, "plastic" look that lacks film grain. The image remains sharp, natural, and cinematic.

The LG C6 has taken a really big step forward here. 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 big plus, because in this area LG’s processor this year performs excellently. The "Smooth Gradation" feature works especially well. With heavily compressed material it can effectively hide ugly tonal transitions and artifacts that often appear, for example, in lower-quality streaming. It’s best to leave it set to "Low." Then the improvement is clear, and the TV doesn’t yet start blurring fine details. Higher levels smooth the image more, but can already remove some of the natural texture of objects on the screen. The upscaling itself also performs very well. Lower-resolution content is sharpened properly, edges look clean, and the processor quite effectively rebuilds fine details. In this regard the C6 is already very close to LG’s best TVs, and the differences compared with the G6 are small.

The Sony Bravia 9 II's specifications don't list staggering refresh rates above 120 Hz, which some more demanding PC gamers may view as a drawback. However, in everyday use, during movie sessions, playing console games, or watching sports, it's really hard to find any complaints about motion smoothness. The VA-type panel used here does show some slight, inherent smearing typical for this panel type, but excellent Motionflow motion smoothing algorithms come to the rescue. In the system menu you'll find sliders for blur reduction and smoothing that let you precisely tailor the motion characteristics to your preferences.

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, sports, or consoles we'll of course use up to 120 Hz, but even then it's hard to fault the motion clarity. As you'd expect from an OLED, the panel's response time is almost instantaneous. Moving objects therefore don't leave the characteristic smears you still see on LCD TVs. This is particularly noticeable in sports and fast-paced games, where the picture remains very clean even during dynamic motion.

For movies and TV, LG also provides the TruMotion motion-smoothing system. In the user settings you'll find two separate sliders. De-Judder is mainly for low-frame-rate content, that is primarily 24 fps films and series. It can slightly reduce the characteristic judder, or be set higher if you want a much smoother image. De-Blur is useful for higher-frame-rate material, mainly sports broadcasts and 50/60 fps television.

Apart from a fairly serious design oversight, limiting the platform to just two full HDMI 2.1 ports, the Bravia 9 II offers almost all key gaming features available on the market. Sony has already accustomed us to such a rich package in its previous models. The list of supported technologies is very long. It includes automatic low-latency mode (ALLM), variable refresh rate (VRR), as well as a proper implementation of the HGIG standard and the Dolby Vision format specifically designed for gamers.

LG has focused heavily on gamers for years, 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 up to 165 Hz. It also offers VRR from 40 to 165 Hz, ALLM, and properly working HGiG. A big plus is Dolby Vision support for games, so the Xbox Series X can use that format without sacrificing game mode. The package is rounded out by a Game Bar that lets you quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is one of those TVs that’s really hard to find fault with. Whether you play on PlayStation, Xbox, or PC, practically everything you could expect from a modern gaming TV is available here.
