When it comes to blacks and contrast, we must be honest – this is the area where the differences between QD-OLED and WOLED panels are virtually non-existent under typical cinematic conditions. We confirm with full responsibility: the Samsung S85F equipped with a WOLED panel achieves amazing and unparalleled results in this respect. Regardless of the scene being watched – whether it's a dynamic action movie or a dark thriller – we receive infinite contrast and perfect black that we expect from any OLED television. These are results that can impress even the most discerning cinephiles. It is worth emphasizing that such deep, absolute black can only be offered by televisions with organic panels. In cinematic conditions, as we see in our measurements, the level of black luminance is zero. So, if you dream of a screen that can "switch off" the light in a scene just as effectively as an independent cinema in a dark room, we are pleased to state that the S85F, also in the WOLED variant, is one of those televisions.
Let's get to the point, which is what is most important in the Mini LED panel: black levels and contrast. The Xiaomi S Pro 2026 is built on a VA matrix, which already promises deep blacks from the start. Adding to that is the Mini LED backlighting with a very large number of local dimming zones. In the 65-inch variant we tested, we counted as many as 532. This is a solid number that should provide precise control over the backlighting. It should be noted that this number is proportional to the size – by choosing the smaller 55-inch variant, there will be correspondingly fewer zones, and in larger models, more.
So, how does the black level perform on the S Pro 2026? The answer is complex.
Overall, it is really quite good, and we see a clear improvement compared to the problematic model from 2025. As you can see from our measurement charts, the results are sometimes spectacular. In most of the film scenes we measured in SDR (standard dynamic range), the contrast could be confidently described as very good and even comparable to designs three times as expensive. Well, it could be... and here we come to the paradox of this model. The issue is how the television manages the zones in scenarios other than SDR. As soon as we feed the television a higher-quality signal, such as an HDR series or Dolby Vision from streaming platforms (Netflix, HBO Max or Disney+), something strange happens. We have the undeniable impression that the television suddenly... forgets that it has been equipped with local dimming zones at all. As can be seen in our video below, the black levels in such scenes resemble more shades of dark grey or navy blue. Additionally, there is a subtle flickering of the entire screen. This is a level we would expect from televisions entirely devoid of a local dimming system. It seems that Xiaomi decided to fix one, but key, flaw of last year's 2025 model over the course of a year. And they succeeded – we no longer have the annoying "zone disco", the image is stable. It's just a shame that when consuming content of the highest quality (HDR), this entire advanced system becomes completely useless.
