The person doing the color grading for Star Trek had a monitor that displayed colors much closer to the iPad 4 than the Mini. So the iPad 4 displayed colors as they were designed to be.
It's fine to disagree with that person's color grading choices, though.
The Colourist on Star Trek would have actually used a calibrated monitor that would have been perfectly flat colour-wise (closer to the mini). If their monitor was closer to the air, the colours in star trek would seem overly flat & washed out in cinemas, HDTV's etc.
