SONY Bravia 9 II XR95M2 vs LG OLED B6

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 LG B6 is a moderately bright OLED. After calibration it reaches about 800 nits, roughly 200 nits more than last year’s B5. That’s thanks to the new budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR in many scenes look fuller than on last year’s lower-tier OLEDs. That doesn’t mean the B6 has no limits. In very bright shots, when a large part of the screen is strongly lit, brightness can drop below 400 nits. This behavior is typical for OLED TVs (especially those from this segment) and that’s when you see the biggest difference versus more expensive models. All things considered, we rate the B6’s results as really solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that you can really feel the step up from ordinary SDR in films.

Color gamut

Using the OLED SE panel has slightly affected wide color gamut coverage. Compared with last year’s model, results fell by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn’t mean the colors on the LG B6 are weak. In most movies and series they look lively, well saturated and simply pleasing to the eye. You only notice a difference in very bright, highly colorful scenes. Then colors lose some intensity compared with QD-OLED panels. This comes from the WOLED panel construction. Besides red, green and blue subpixels it also uses a white subpixel that helps boost brightness. It comes at a cost: at very high luminance some color is effectively “diluted” by the white light, so saturation of some colors can be slightly lower. In everyday use this isn’t a big issue, but you can notice it in the most demanding 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.

We tested the LG B6 in Filmmaker Mode, which is the best picture setting available right out of the box. ISF modes deliver very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of those modes is, after all, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. With SDR content, the factory settings perform really well. Color errors are small, gamma behaves properly, and the image looks natural during ordinary viewing and does not seem overly "pumped up." It's a bit worse with HDR. When you play that kind of content you can quickly see that the white balance hasn't been set perfectly. Too much blue and red causes the image to shift toward a slightly pink tint. This is also confirmed by measurements of the color gamut and the ColorChecker, where samples clearly drift in that direction. It's not a flaw that completely ruins the picture, but you can notice it in HDR films. So people who care about the most faithful image should consider the calibration we describe later in the review.

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.

During calibration we focused primarily on HDR content, because that's where the factory settings required the biggest corrections. We didn't neglect SDR mode, though, which after adjustment was brought almost to perfection. Colors are very accurate and brightness is handled as it should be. The biggest improvement in HDR came from correcting the white balance. After removing the excess red and blue, the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colors that had been shifting toward magenta improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. The LG B6 can therefore deliver a very accurate image, especially for the manufacturer's entry-level OLED model.

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 B6 handles lower-quality sources very well. Much of the credit goes to effective digital image processing, which can mask some source imperfections without overly smoothing the whole scene. The feature "Smooth Gradation" proves particularly useful. It can significantly reduce posterization, which we mentioned earlier, especially in darker areas of the image. The safest choice remains Low or Medium. The function still effectively smooths harsh tonal transitions, but does not yet interfere too much with fine details. The most dedicated purists can, of course, leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a good amount of detail, and the image is neither overly sharpened nor excessively blurred. Some limitations become noticeable only with very poor sources below 720p, where the smallest subtitles and fine elements are not always perfectly sharp, but this is true for almost every other TV on the market.

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.

One of the biggest advantages of OLED panels is their very fast pixel response time. This keeps the image sharp and prevents the visible smearing that often appears on LCD TVs. However, there is a downside. During slow camera pans, motion can look more choppy than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 you can easily soften this with TruMotion. With the motion smoothing properly adjusted, you can achieve smoother motion without giving the picture an excessive soap-opera effect.

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 OLED B6 offers a powerful set of advantages for gamers; it's simply a complete platform for PS5, Xbox Series X/S, or a solid PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can skip the annoying cable swapping when you want to connect several newer devices at once. We get the full suite of sync technologies – from classic VRR to G-Sync and FreeSync. The screen seamlessly matches the refresh rate to the frame output produced by the console or graphics card. Of course ALLM is included: the B6 automatically detects a running game and immediately cuts input lag to a minimum. HDR handling is also excellent. The TV supports Dolby Vision, and a properly implemented HGiG standard means that after an initial calibration in the console settings the picture won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on top is the Game Bar. Instead of digging through the full menu during gameplay, one click lets you adjust shadow visibility, tweak selected settings, or simply check the display’s current operating mode. All of this makes the LG B6 a great choice for gamers.
