Interesting choice! I think I may prefer mini led to OLED tbh, my brother has an OLED tv and he always worries about burn in to the extent he won’t really watch sports or news channels because of the static content, hes probably over panicking but he doesn’t want to risk it. Me on the other hand with the mini led I don’t have to worry about that, plus HDR looks amazing on the iPad whereas oled can struggle to reach the same brightness. OLED does have inkier blacks but I think the difference is fairly negligible, blooming is there but not in 99% of use cases.
what I think future generation of iPad Pro’s will have is more dimming zones i.e. Currently there are 4 mini leds to a dimming zone, ideally they could go down to 1 led is it’s own dimming zone, bringing it even closer to oled with less blooming etc
just my 2 cents
