[Tig] MacBook Pro colorimetry

[glenn chan]

I have a LED-backlit MacBook Pro (Santa Rosa).  By looking at its ICC
profile, you could see that the color gamut is significantly smaller
than Rec. 709 / sRGB.  Colorsync will apply color management to map
colors inside... there are some banding-like artifacts on gradients.
There is this clipping-like effect if you have gradients going into
full saturation.

I presume this is because the MBP uses only white LEDs, not LEDs for
red green and blue.  I'm guessing this is to make the screen brighter
(helpful in laptops) and color uniformity would be easier to achieve.
