The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price class, although it is slightly dimmer compared to the QD-OLED version. The difference is not as pronounced as in last year’s F series, where gaps could reach as much as 500 nits. Here the specs of both panels are very close, and differences in peak brightness are only about 100–150 nits. In small-area measurements, the S90H on the WOLED panel easily reaches levels close to 1500 nits. That headroom lets it portray HDR dynamics phenomenally—specular highlights, reflections or explosions have the right punch, just as the creators intended in the post-production studio. As with most OLED displays, when a very bright scene fills the entire screen, the protection systems that safeguard the panel kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.
Color gamut coverage
The biggest difference between the two S90H variants lies in color reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, colors at very high brightness don’t achieve quite the same intensity, and the volume of the wide color gamut is somewhat more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches nearly 99%, which means that in the vast majority of real film scenes both variants will deliver almost identical images. The true gap only appears in rarer, particularly demanding productions that use the ultra-wide BT.2020 gamut. Due to the WOLED panel’s design, coverage of that standard is about 15% lower compared to the S90HAT with a QD-OLED panel, so the brightest, heavily illuminated HDR colors may appear a bit less vivid.
Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 series. In the same movie scenes the previous year's model stayed closer to about 700 nits, while the S85H can reach around 800 nits. Of course this isn't a change that completely transforms the HDR experience, but that extra headroom is noticeable especially with small highlights, reflections, and stronger special effects. Around 800 nits is already a very good result for an entry-level OLED and in most films it's enough for HDR to have the right impact. Bright elements can clearly stand out from perfect black, and that contrast still does most of the heavy lifting here. You should remember the typical limitation of organic technology, though. When a very bright scene covers a large part of the screen, brightness can drop by almost half. This is the result of the panel's protection mechanisms, which limit its power with large bright areas.
Colors
The S85H can produce very pleasant, saturated colors and in most HDR films it looks really good in that respect. We measured roughly 95% DCI-P3 coverage, so the palette most often used in movies is reproduced to a very large degree. Skin tones, greens, and stronger reds still have appropriate intensity, and during normal viewing it's hard to fault them. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was around 70%, a bit less than in previous-generation WOLEDs and noticeably less than in QD-OLED panels. In films this isn't a major loss, because most productions rarely use such highly saturated colors. You notice it more often in games, where developers are much more likely to employ more intense colors.
