Here is a professionally calibrated display, with an "iPad 3" in front of it:

The Galaxy Tab 10.1 screen is blue (8380K) and your other displays must be as well, from that comparison.
All that image proves, is that the ambient lighting did not match the iPad display.

Note the horrible orange colour of the LCD. It doesn't look like that at all to the eye, but illustrates why you cannot judge how "white" a display is compared to the bezel.
Pretty nice white tones you have their on the Ipad3
