You will not notice much difference if you open up more, either. All this based on you idea that a 5% drop from, say, 1200 is the same, visually, as 5% drop from 2400, which is a very bold assumption and flat out wrong at moderate viewing sizes.

And where exactly is that assumption?

You are applying 5% threshold for low density sensors and for higher one. This does no prove existence of a limit but let us play that game for a moment. Why fixed percentage? Why not measure it absolute terms? Why not on a log scale?

Now, one can say that at a higher resolution 5% matters less because we cannot benefit much from that high resolution anyway, depending on how we view the result, of course. Then you should choose, say, 10% threshold at higher densities instead. And the results may surprise you.
