Samsung S85F (WOLED) vs SONY Bravia 9 II XR95M2

For most of the time, let's say in 90% of film scenes, viewers won't see practically any difference between the S85F versions. When small but very strong light points appear on the screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (like the smaller S85F) performs wonderfully. Our measurements showed peak brightness at around 750 nits. We can confidently state: this is an excellent result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen has to shine at full power brightly. Examples include a slide with a white background, a ski jump scene, or our test sequences (5) from the movie The Meg. And here, unfortunately, the results diverge quite significantly to the detriment of the WOLED panel variant. Our measurement equipment was able to measure a maximum of about 250 to 300 nits of brightness in such conditions. Just to be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colors. And here we also have to be honest – QD-OLED has a design advantage. Why? It’s simple. QD-OLED creates colors from three components (red, green, and blue) and does not need an additional white subpixel. The WOLED panel we are testing uses this white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider color palette, and the colors are a bit "cleaner." But let’s be clear: it’s not that the colors on this WOLED panel are bad! On the contrary, they are actually very good. Coverage of the DCI-P3 film palette at 97% and 71% for the wider BT.2020 palette is still a high standard. We just have to honestly admit that this few percent advantage in color coverage is on the side of QD-OLED technology and may be noticeable in very specific moments.

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.

When it comes to factory color reproduction, our test sample in SDR mode suffered from a slight deficiency in red and yellow color. This resulted in a subtle yellowish tint visible in the shades of white. However, this is not the biggest problem with the S85F. Similar to the QD-OLED panel variant, the biggest issue with this model is the way it presents HDR content. When we look at the EOTF curve graph, it is easy to see that the television has quite significant problems with overly brightening the image. This causes the final picture in many scenes to become very unnatural.

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.

After calibrating in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs exemplary, and its color reproduction errors do not exceed a value of 2, which is an excellent result. A bit worse, although still very good, are the HDR quality contents. While we were able to eliminate a significant unnaturalness in the image caused by too high a positioning of the EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has slight issues showing all the details in the image. We must point out right away that it is highly unlikely that an average viewer would notice any shortcomings in the image. The final effect after calibration is rated as exemplary.

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.

The processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterization (the "stepping" effect of colors), even with heavily compressed materials, such as from streaming services. However, using this feature requires making a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be the golden mean, not causing visible loss of important details, so we can recommend it. However, we advise against using the "High" level, which removes not only noise but also desired details, such as texture or structure of objects on the screen.

The scaling (upscaling) process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we observed is occasional, slight aliasing on the edges. The television also still exhibits characteristics typical of this manufacturer, such as active "overscan" (slight magnification of the image). This should be kept in mind, especially when watching older materials, as it may result in a minimal cropping of the original frame.

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 S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, meet expectations: smoothly, sharply, and without loss of clarity. A key role here is played by the instantaneous pixel response time, which is a natural advantage of OLED technology. Transitions between frames are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, like a ball on the field or a car in a chase scene, are clear and devoid of the characteristic motion blur typical of LCD panels (the so-called "tail").

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.

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.
