I have a M4 iPad Pro and I love the device. However, if I could have bought the same specced iPad with the prior iPad Pro screen and Face ID I would have saved the money and not bought the OLED screen. The OLED screen, to me, is a needless expense with a very marginal benefit. I chose to buy one because I could afford it, but the previous screen was just as good to my eyes.
I thought the OLED screen wasn't that big of a deal until I tried to watch the new season of Silo on my LED TV or old iPad Pro 🤣 can't see nothing on those.
