On my GNU/Linux box, I use a gamma of 1.8 for my display, which works
quite fine and is not too bright... So may value 2.2 is intended to
compensate uncorrected displays.

Hmm, if the energy gets distributed evenly (this is, the gamma is
correct), this shouldn't be a problem since the gray values of, say,
two 50%/50% lit pixels sums up to 100% as if it were a single black
pixel.
