Just to clarify from my readings, he measured the color correction of the display as is, without changing any profile or white balance and the DeltaE 2000 value is 7.11 which is pretty bad i.e. far from accurate colors (anything <5 is considered good and <3 are exceptional). However, what he failed to mention is that even Galaxy S7 has the same DeltaE value when measured on any retail unit (many of you know that the default color profile i.e. adaptive mode is what makes the Samsung AMOLED displays punchy and saturated). Its only when changed to the basic mode, the Galaxy S7 becomes very accurate (with 1.7-2.3 DeltaE). Considering Oneplus is basically using the same SAMOLED units in Galaxy S7 with some tweaks, I'd think changing the color profile/mode should yield great results similar to the Galaxy phones. I'm not sure if changing color profile/mode is permitted in settings, but he did mention Oneplus reverted back to him quickly, saying they'll change the default profile in a later OTA update.
