No it doesn't. I bet you could not tell difference between 1024x600 and 950x540 if the screen size was the same. Well, if you have some test pattern with exactly 2 pixel wide lines in original material, then your approach would probably lead to better results. But if you watch something else than test charts, difference won't be visible. In normal use, more pixels would be better so I would take 1024x600 over 950x540 any day.
