According to DisplayMate's recent findings, the Samsung Galaxy S20 Ultra boasts a "very impressive excellent top tier world-class smartphone display" with close to "textbook perfect calibration accuracy and performance" that is "visually indistinguishable from perfect," ultimately awarding no less than 12 awards to the phone.
The noted publication also awarded the Samsung Galaxy S20 Ultra with A+ rating, with a slew of "record" highlights. These include its exceptionally high contrast accuracy and intensity scale accuracy, a peak luminance that is independent of the on-screen image content, color accuracy and intensity scales, DCI-P3 Natural Mode with a very accurate standard DCI-P3 color gamut, High Brightness Mode with automatic brightness on, and sRGB Natural Mode with a very accurate standard sRGB/Rec.709 color gamut.
DisplayMate also noted that the Samsung Galaxy S20 Ultra's new display is 14% brighter than the Galaxy S10 phones, right with the aforementioned High Brightness Mode which improves its screen readability in medium and high ambient light levels. Consequently, this mode allows the screen to produce between 823 nits and 1,342 nits.
Additionally, the screen on the Samsung Galaxy S20 Ultra is said to be tuned to hit the maximum at a lower ambient light level than before, with 20,000 lux (outdoors, but not in direct sunlight). Meanwhile, the Samsung Galaxy S20 Ultra's Super Dimming Mode allows it to go way down to 2 nits while still keeping the 24-bit color. As it is, this drops to 1 nit when the Always On Display mode is activated in the dark.

The Samsung Galaxy S20 Ultra uses a 6.9-inch Dynamic AMOLED 2x Infinity-O display with a high resolution of 3,200 x 1,400 pixels. One of its significant upgrades, of course, is the 120Hz display refresh rate. Other highlights of the phone's display include support for HDR10+ and Corning Gorilla Glass 6.
Finally, DisplayMate noted that OLEDs are still bound to continue its dominance on top-tier smartphone displays for the next three to five years – with the reasons for its popularity being outed for years now. OLEDs feature fast response times, better viewing angles, high refresh rates, and low power consumption.
Nevertheless, the increasing demand for OLEDs would ultimately put considerable pressure on supply.
