Actually that's a bit circular.  LAB is designed with a definition of L
(named luminance) and a gamma such that L increases uniformly as we step
from pure white to pure black.  When we look at L values, for say Gray Gamma
2.2, we simply find that they don't have the same characteristic.  But in
the end, its simply all about gamma...ahhh contrast!
