I don't care about OLED wearing out. Had one of the first phones with OLED for about 5 years, the phone died because of water dip, but no changes to the screen. I'm using now LG OLED TV as a monitor since a year, no sign of wearing out, and mind you I do use it ~10 hours a day.
I don't know how they achieved that but the blacks on OLED are perfect, despite "glossy" finish. Sitting in front of OLED screen is like looking into a black hole, I can only see a faint ghost of me but heavily blurred and "deep in the black shadows".
Ideally, I would like to get a mate glass for an OLED screen
