I came from a 7+ and have had similar experience with the 8+ screen. People say it is the same but yeah it does seem so much richer. Maybe it is just True Tone I am not sure.
Whatever it is I was surprised when I booted the 8+ up. It sort of seems closer to what my S7 Edge was in color than my 7+.
I am pretty happy with it and happy to hear somebody else thought the same thing.
My 8 Plus screen is the best iPhone screen I’ve seen. Very nice. Colors look punchy, but accurate. I’m curious if the X display will be as accurate, given the fact that OLED is generally unnaturally saturated.
