Why worry. Are you going to be staring at a phone screen a lot? I don't. The iPhone's screens are superb for color gamut and reproduction. OLED is nice, but most people unless they are comparing them side-by-side really don't know the difference and most other phones with OLED are not useable in full sun. iPhones are with LEDs are far better in sunlight and the OLED iPhone X is much brighter so it will be usable in sun as well.
But, then, I knew you'd come up with an excuse.
Yes i do look at the screen a ton. And yes there is a huge difference. Not an excuse, but a reality. Why couldn’t apple update the screens in the 8? All other flagships use some sort of oled.... And it does matter or iPhone X would have kept lcd. Ice had oled and amoled for about 0 years now. I can’t go backwards. It’s the most important thing to me... So much so I’m consider android.
