This is not surprising actually,Samsung are the king of high quality displays, I am actually surprised Apple didn’t go OLED on their iPad Pros back in 2018.
Don’t get me wrong, I absolutely love using my 2020 iPad Pro 11”, I am typing on it right now and think it’s overall the best tablet out there as of writing this but Display wise I would say Apple definitely leave something to be desired.
If someone is coming from a Samsung Tab S7+ or S6, they will be coming from a Super AMOLED HDR10+ screen and in the Tab S6 case a much higher PPI screen at that, so the iPad Pro screens may actually look like a step back.
On the other end one can express how shocked they are at the poor software landscape after all these years in Android Tablets still is, which leaves much to be desired. There is no perfect tablet out quite yet.
I hope the upcoming iPad Pros will take iPads to a new level in terms of Displays as the current crop of iPad Pros definitely is not the best out there in that area, IMO.
