These so called "screen issues" shows you how used to everyone is with all these over saturated screens. Most people do not calibrate their TVs at all and this is why "accurate" colors look so dull because of this norm of the displays coming out of the box with over saturated colors and "dynamic Contrast" enabled. These color settings could easily be adjusted by software and Google will probably add the ability to in later updates.
Also the blue tint I imagine is because of the polarization of the display and for a device that you normally do not look at from an angle I don't see this as much of an issue.
