Eh, it's the lesser screen, not a shitty screen. It still looks good to my eye, and going by XR sales I'm guessing most people don't really mind it either.
I'll agree with you it's not the best screen Apple could have put on it, but it's not a shitty one.
Well, it's not like putting OLED in 11 will cost them millions. They just get a bit less profit which they still choose not to do because majoritor of the people wouldn't care ( they might be able to tell the different if they ever use OLED before, the colour depth and black level is night and day ).
It's absurd when people praise Apple for reducing the price and say this is the most valuable/worth the money model they could ever push out. I mean the phone itself is still expensive consider technology they put in there. The proper upgrade one is in pro version which is still up at 1000+ price point.
Can't blame Apple though, they do what is best for them ( making money ). And there are people who are happily to pay for that. Demand and supply after all.
