The best pixel shifting can do is blur the edges of the burn in. It doesn’t prevent the burn in from happening.Modern OLED tech is exceptionally resilient to burn in these days. Not saying it can’t happen - but it takes thousands of hours on a static image at max brightness to start seeing burn in on something like a Nintendo Switch OLED - and burn in is incredibly rare on iPhones. Most devices have built in tools like refreshing and pixel shifting that’s invisible to us but really keep the burn in risk to a minimum even with static elements like a menu bar, etc.
Computer usage has lots static elements on display for a long time, which is the worst use case for OLEDs
