The Hisense UR9S is without a doubt a show of strength from the Chinese manufacturer when it comes to luminance. On a synthetic test pattern the panel reached as much as 2600 nits, which is an impressive result. But you have to clearly separate lab results from film realities. In real material the UR9S behaves much more restrained. Peak brightness in balanced scenes hovers around 1500 nits. In demanding, dark shots—where the algorithms must at the same time preserve deep blacks and precisely light small details—brightness can drop drastically, even down to around 400 nits. The gap between the chart and reality is therefore huge. This is a direct consequence of conservative local-dimming behavior. When a bright object occupies a large portion of the frame, the system can easily maintain a high luminance. But in night scenes the priority becomes protecting black levels and fighting the halo effect (unsightly glows around bright edges). To avoid degrading contrast, the TV drastically limits its light output. Even so, the UR9S can still produce a very powerful, engaging HDR effect that impresses in bright, spectacular sequences.
Color gamut coverage
On test patterns the Hisense UR9S performs excellently in terms of color. DCI-P3 coverage is nearly 100%, and BT.2020 coverage reaches 93%. Those are figures even the best QD-OLED TVs don't achieve. But again, synthetic measurements are one thing and movies and series are another. In real-world scenes the numbers fell to 93% for DCI-P3 and 81% for BT.2020. That's still great, but the advantage of RGB Mini LED is no longer as dramatic as manufacturers promise in marketing materials. You could even say their capability is now close to TVs equipped with quantum dots, the so-called QLEDs. Why does this happen? Largely, color reproduction depends on how the local dimming zones operate. When a highly saturated color appears next to white or another, more complex element, a single zone must handle both parts of the image at once. Under those conditions the backlight cannot maintain extreme saturation of a given color on the screen, because the emitted light takes on a character closer to white. Hisense refined this quite well in the UR9S, but still not enough for the TV to sustain such high color saturation in every situation.
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.
