It allows my shows to be a lot bigger. Yes, you have the notch. but otherwise full screen.
When I first got my iPhone 12 Pro Max I watched a bit of the movie 2001 from my iTunes library. I guess I double-tapped the screen inadvertently, because I don't think full screen is the default. Anyway, was thinking it was cool to use the full screen on a phone with a "Cinemascope" aspect ratio. Then a scene with lighter colors came and I became painfully aware of "the notch". I actually laughed out loud, thinking "Kubrick would be rolling in his grave to see that happen to his composition"! 🤣
So, no thanks, I prefer the smaller "notchless" view.
