Thanks for your words of warning - I've also read quite a bit about the negative consequenses of turning off that (and other similar) settings. The decision to try turning it off wasn't completey arbitrary though; during my many google searches for display errors on Samsung devices, I ran across several discussions about flickering screens (mainly related to the Youtube app), where the problem disappeared when that exact setting was disabled. So I thought I'd give it a shot and see if it helped in my case as well (though, of course, a flickering screen isn't exactly what I'm seeing..).

I'd also be very happy if anyone else would try testing this out.
