It doesn't have to be. XYZ can be converted to/from CIELab without
loss of any relevant information, and Lab has considerable advantages
for things like table interpolation.

You're mixing different things up. CIELab is not the perfect perceptual
space, and it's correct to say that it has some noticeable distortions
in some areas, but, it's far, far more perceptually uniform than XYZ !
