My Nexus has a good screen that doesn't suffer from being washed put and has great viewing angles. It does however has a warmer tone than I'm used to. The app I found tonight is called Screen Adjuster. I just increased the blue level to 15 and now the whites have a little bit of a bluish tone like my G Nex. There are adjustments for green and red scales if that's your thing. Havent tested the battery effects but I can tell right off the bat that this app only takes up 17mb of RAM. Gve it a try, let me know if you have any tips to share!
