I have a doubt, from which Samsung tab are you coming from
honestly, I used to use a Samsung Galaxy Tab S1 and I switched to apple as their software support was amazing and the apps were really good, that too I went for the cheapest iPad(5th gen) in 2017, and yes the display on them is awful cause of the delamination gap but then I've tried and used the 2018 and 2020 Pro's and honestly they have a really good screen
I get it amoled is superior to LCD but then you have to keep in mind that Apple is a company that sold a $749 phone with a really good quality LCD whereas competitors are struggling to keep up with the color accuracy in their OLED Panels
I'm not an Apple Sheep like the others, I love all my tech products equally, but there is something good with Apple's Displays always even if its LCD
take a look at the Mac, can you complain that they have an LCD in it, you can but then others are doing worse than apple in that space
