It's not about "appreciating". It's that it doesn't matter. Everyone talked about retina resolution, then about "true colors".
Today we have Samsung making all the screens.
The point is, nobody except professionals care.
The colour reproduction on Samsung phones is just awful after spending so much time on MacBooks and iPhones. Over saturated and as you increase brightness it washes everything out.
What makes the screen different is that the colours aren't oversaturated like Android phones. It was identical to the iPhone 8 screen (LED) only significantly brighter.
From what I've read what makes it better are things like the reduced blue-shift that occurs when moving the phone and the significant reduction in burn-in effect. But what most people will think is that it is the colours that make it better. Even though that could largely be software.
I can't believe that. I just can't.
All iPhone X reviews mention the screen tech difference, all of them say how they don't notice a difference.
