The OP's issues seems to be with ICS UI design, not the Nexus screen.
Having said that, I've noticed a bunch of comments like oh the Nexus screen is way superior than the OG or is the best out there. With those statements, I have to strongly disagree.
If you are rating a screen purely on how crisp things look (i.e. pixel density and clarity), then the Rezound is easily the best display and the OG droid screen still beats out the Nexus due to the pentile display on the Nexus. I played extensively with the Galaxy Nexus, the Razr, the Rezound and my OG Droid, and the Rezound was easily the crispest and clearest display, especially when viewing small text. The OG droid was better than the Nexus at displaying small text and the cross-hatched pentile arrangement was visible (albeit nothing as bad as the Razr) giving the black text a slightly less solid - grey appearance. I am more sensitive to this, and it is easy for me to notice these things.
As far as colors go, it is a personal choice. Some like the saturated colors on AMOLED to LCD, others prefer the slightly more accurate color tones on the LCDs. Certainly, the AMOLED displays have more "pop" to them, but for me, the crispness and clarity of the display matters the most.
