At first glance, one might assume that Samsung would simply hold the line and continue to use the same stellar Galaxy S8/S8+ Infinity Display panels on its latest flagships. However, Dr. Raymond Soneira, President of DisplayMate, says that Samsung has made improvements to both absolute picture quality and absolute color accuracy of the OLED panel through the use of precision factory display calibration. In fact, Soneira says that absolute color accuracy is now "visually indistinguishable from perfect."
That's definitely high praise for the Galaxy S9's display, and Samsung was able to make improvements in other areas as well. The display is now 20 percent brighter than on the Galaxy S8 in High Brightness Mode (1,130 nits). When it comes to display accuracy, the Adaptive Display mode allows the Galaxy S9 to hit 141 percent of the Standard sRGB and 113 percent of the Standard DCI-P3 color gamuts.
We should also note that the Galaxy S9 now includes a new user-adjustable white point for the color balance slider controls. Using these controls, the white point color temperature can be adjusted from 6,800K up to 8,600K (which has a more blueish tint). And as you might expect for a high-end flagship released in 2018, the Galaxy S9's display received Mobile HDR Premium certification by the UHD Alliance.
DisplayMate continued to lavish praise on the Galaxy S9, writing:
The Galaxy S9 is the most innovative and high performance Smartphone display that we have ever Lab tested, breaking and establishing many new Display Performance Records that are listed above. The Galaxy S9 delivers uniformly consistent all around Top Tier display performance and receives All Green (Very Good to Excellent) Ratings in All of the DisplayMate Lab Test and Measurement Categories – the first display we have ever tested to get All Green in All Categories. The level of display performance and excellence has been increasing each year, and the Galaxy S9 has raised the bar higher...
DisplayMate crowned the iPhone X as having the best performing smartphone display that it had ever tested following its release late last year. And if you recall, that display is manufactured by none other than Samsung. Given the year-over-year improvements that Samsung has made in its OLED technology, we can expect that the upcoming Galaxy Note9 and this year's iPhone X successor will only further move the bar when it comes to display performance.
