The Samsung Galaxy S9's color accuracy is "Visually Indistinguishable from Perfect"
The newly announced Samsung Galaxy S9 continues the tradition of laying claim to the best display crown by display testing and calibration firm, DisplayMate. The firm seems to be highly excited about the Galaxy S9's display and says that it is the best smartphone display it could ever test. The high display performance is attributed to Samsung refining OLED technology with each generation making it brighter and more color accurate.
DisplayMate notes that the Galaxy S9 sets new benchmarks in having the highest absolute color accuracy of 0.7 JNCD making it "Visually Indistinguishable From Perfect". JNCD or Just Noticeable Color Difference is a metric to quantitate on-screen color accuracy in comparison to the eye's sensitivity to that color. Another first for the S9's display is that it has the highest peak brightness in a smartphone till date (1,130 nits) and covers a 113% DCI-P3 and 141% sRGB color gamut. Considering the S9's overall display performance in its battery of tests, DisplayMate says that it is "almost certainly considerably better than your existing Smartphone, living room 4K Ultra or HDTV, Tablet, Laptop, and computer monitor". That's a pretty high accolade and Samsung can surely pat themselves on the back for this achievement. While most of the S9's display innards have been directly borrowed from the last year's Galaxy S8, it is the fine refinements Samsung has done to the overall experience that is being lauded. The Galaxy S9's display is also more resilient to every abuse so you're definitely getting your money's worth at least when it comes to the display prowess of the device.
The S9 has a 3K 18.5:9 (2960 x 1440) display and DisplayMate notes that 4K on a smartphone display has "no visual benefit for humans". The firm stresses that OEMs should focus more on minimizing variations in color gamut, saturation, and contrast due to changes in ambient lighting instead of racing to cram more and more pixels.
