My Xoom is 3G and rooted. LCD Density did not work but LCD Resolution did do the trick. I tried Backlight Filter and it was too difficult to get the screen looking right so I tried Color Filter which was a bit better but this isn't what I really need. I noticed that by default my screen leans more to blue and I just wanted to adjusted the color. Color filter darkens the screen as I adjust the color which means I have to increase brightness and that will only lead to more battery drain. So I abandoned color correcting the screen. On another note, I am not sure if it's because of overclocking and resolution change but my videos play with much better color. I wanted to credit the new install of Dice Player but I don't recall colors looking like this when I first installed it.
