Hmmm, how far does your belief go with this though? Let's try pushing the extremes a bit...
You seem to be saying a lower res smaller screen with a higher PPI is going to give a more detailed image ?
Screen 1
480x480 pixels, 1"x1"
230,400 total pixels, with 480 PPI
Screen 2
4,096x4,096, 10"x10"
16,777,216 total pixels, with 409.6 PPI
following from your logic screen 1 is the better screen? All else being equal.
Somewhere your argument breaks imo.
Detail = information = pixels.
Screen 1's quality is higher because of the higher PPI; you will see more details and bigger zoomed out picture on Screen 2 because of its sheer size.
