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.
In terms of brightness the Samsung R95H shows that we’re still dealing with a top-tier TV, although the results aren’t always as spectacular as you might expect from a flagship Micro RGB model. In synthetic tests the TV can exceed 2,400 nits, so it definitely has plenty of headroom. Importantly, it can sustain high brightness even when bright elements occupy a larger portion of the screen. In real movie scenes the situation is a bit more complex. The R95H most often reaches around 1,000 to 1,400 nits, which still delivers a very good, strong HDR effect. Bright sunlight, reflections, or lights can look truly impressive, and the TV has enough power for HDR to be clearly distinguishable from regular SDR.
The problem appears mainly in very dark scenes with single, small light sources. Here the local dimming algorithm favors deep blacks and reducing the halo over maximizing the brightness of such elements. As a result, small lights can be noticeably dimmed. Overall HDR performs well, but not without limitations. The R95H has huge brightness headroom, especially in larger and brighter parts of the image, but in difficult, dark scenes its capabilities are mainly limited by how the local dimming operates.
Colors
Colors were meant to be the biggest revolution enabled by the RGB backlight, and the R95H does show considerable potential here. The assessment is not, however, as simple as synthetic measurements might suggest. On test charts the TV performs superbly. BT.2020 coverage reaches almost 94%, and DCI-P3 98%, so especially strongly saturated reds and greens can look really impressive. The picture changes a bit when, instead of test charts, we start measuring real movie scenes. Then BT.2020 coverage drops to about 87% and DCI-P3 to 93%. It seems that with more complex imagery the RGB zones are not always able to maintain the same high color saturation as on simple charts. They are still saturated, but the advantage of the new backlight is no longer as large as the manufacturer's numbers might suggest.
