I'm glad that Apple philosophy is to want you to focus less on phone screen, by not have this feature or by having Apple Watch, and I'm glad there's no useless feature like this on phone that screen can be burnt in which my wife can accidentally turn on. But on the other hand, on Apple Watch however this feature is truly needed.
Apple want you to focus less on the screen
The reason I like an AOD (and I get that everyone is different) is that it means that I don't have to pick my phone up to check if I have messages, I can just glance down and see. As for burn in pretty much every implementation I have seen moves it periodicallly, more chance of burn in from the status bar or nav buttons.
