- optimal contrast (lowest contrast that blocks go away) for 100% brightness is a contrast of ~7%. Could go a little lower, but then the blockiness starts to manifest
Anyway, for anyone like me that noticed this, try out this free app. I am more than happy to use this workaround and keep my Nexus than go to a locked down device.
I may still file a bug with Google/Samsung on this. Seems like it MIGHT be fixable in software - even if it's just a built in way in ICS to adjust contrast.
cool! glad you found something that fixes the symptom! tried it out and noticed no blueness.

I'm glad you found a fix for your problem though.
it's kinda subtle and you'll only see it if you really look for it. in camera-land, this is like pixel peeping to see how effective the sensor is at producing true black and not having a lot of noise.
I would kinda think that this is a minor flaw within pentile compared to true super amoled plus screens and retina displays.

if you look at the macro shots you can see that the blue sub-pixel actually appears to take a larger surface area than red/green, this could account for the blueness we are seeing.
