SONY Bravia 9 II XR95M2 vs LG OLED B6

The real showcase for the new backlight architecture and Sony’s processor is HDR reproduction. At the official launch the Sony engineers said (not officially 😉) that the Bravia 9 II’s brightness should be almost identical to their professional director’s monitor BVM-HX3110, priced at astronomical sums. Our lab tests confirmed they weren’t empty promises. In synthetic measurements on the L20 test pattern the TV easily exceeded 4000 nits of peak brightness. More importantly, these impressive results translate directly to real film scenes. In most of the demanding shots we tested the screen consistently held brightness around 2500 to 3000 nits. Whether the light was small and pinpoint or flooded almost the entire screen, the HDR effect was incredibly intense.

Colours

Colour is another key pillar of RGB Mini LED technology (Sony’s True RGB implementation). For testing this type of panel we’ve permanently added a new research section to check how TVs handle colour in real-world conditions. Traditional synthetic-chart tests are no longer enough to determine real gamut coverage. From now on we also measure colour saturation directly in selected film scenes by overlaying measurement points. So how do the colours perform?

In synthetic tests the Bravia 9 II posts excellent results. For the popular DCI-P3 space used for HDR, colour-gamut coverage was almost 98%, while for the extremely wide and demanding BT.2020 space our measurements showed nearly 90%. However, in real-world, varied scenes those values drop by a few percentage points. This is directly due to the nature of zoned RGB backlighting. When differently coloured elements or bright white points appear next to each other, light from adjacent zones begins to mix slightly, producing a whitish backlight. This, of course, affects colour saturation, slightly reducing it. It shows that despite Sony’s brilliant algorithm controlling the RGB diodes, that number of zones is too small to eliminate the effect completely.

Is this a reason to complain? Of course not. The Bravia 9 II’s final colour coverage is the same as that of a very good QLED TV, and it’s important to remember: the vast majority of films and TV shows distributed in HDR use the DCI-P3 gamut. In that standard Sony easily maintains very high colour saturation, regardless of the scene.

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

Contrary to expectations and high hopes, the Bravia 9 II we tested straight out of the box showed some issues with its factory calibration. Looking at the white balance charts, you can see it isn’t perfect. In SDR content it mainly lacked the red component, so the picture leaned toward cooler, bluish tones. By contrast, white balance in HDR looked much better in that respect. So where do the visible errors in image reproduction come from? They stem from an 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 significantly too high, at times running very close to 2.8 instead of the reference 2.4. In practice this meant the image was artificially dark and appeared washed out of colour, with details in dark areas (the shadows) completely lost. The opposite was true in HDR material, where brightness reproduction is handled by the EOTF curve. That curve was pushed too high above the correct value, which resulted in the picture being artificially brightened across most luminance ranges. As with every TV we test, we also subjected this unit to professional calibration. You can see the results and how we managed to correct those factory errors below.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

Fortunately, with professional calibration, most of the factory shortcomings of the Bravia 9 II can be effectively eliminated. We managed to precisely correct primarily the white balance and the gamma and EOTF curves. After those adjustments, in everyday use and during movie sessions the TV looks vastly better. The image gained proper dimensionality, the cool tint to the whites disappeared, and shadow details that had previously been lost due to excessively high gamma finally became clearly visible. Although we ultimately assess colour 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 it weren't for the complete lack of an advanced colour management system in the TV's menu.

While a basic white balance correction can be carried out here without issue, the settings lack options for adjusting specific colours. We tried to tackle this from every angle, both using the traditional method from the remote and with dedicated calibration software for Bravia TVs. Unfortunately, that function has been entirely locked. We suspect this may stem from the specifics of the new RGB architecture, which imposes these limitations. It's a real shame, because without it you can't fine-tune colour reproduction to perfection. The inaccurate red, for example, still stands out. Let's hope Sony will fix this shortcoming over time via an update.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED model.

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

However, what earns the most praise in the XR processor's performance is its tonal transition smoothing function. The system can reduce posterisation in heavily compressed material to practically zero. Crucially, the algorithm does this in a very intelligent way. It removes only the irritating digital 'steps' in gradients (banding), but does not blur fine texture detail or create an artificial, 'plastic' look lacking film grain. The image remains sharp, natural and cinematic.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

In the specifications for the Sony Bravia 9 II you won't find dizzyingly high screen refresh rates above 120 Hz, which some more demanding PC gamers might see as a drawback. However, in everyday use — whether during film sessions, playing console games or watching sport — it's really hard to criticise the motion smoothness. The VA panel used here does exhibit some slight, natural smearing typical of this panel type, but the excellent Motionflow smoothing algorithms come to the rescue. The system menu includes sliders for blur reduction and smoothing that let you precisely tune the motion characteristics to your own preferences.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

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

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.
