I do think a lot about the unintentional side effect of low res art. Obviously the artists would have wanted their art scanned and rendered in the game in the highest resolution available, but at the time that was pretty low, but that had the side effect of us as players imagining more details than were there, and mentally inserting a sort of 'graininess' to the art that was quite unintentional, and growing attached to that.
Of course, I'm not saying that's the ONLY difference between the old art and this stuff, but I do think it's interesting that as soon as I pixelate the art, my brain adjusts and goes 'yes, that's an adventure game background like how I remember'
