If you want to "see" a linear gradation between white and black, you should use a L*-gamma-calibration, because the L*-gamma-curve is adapted to the human perception.
Hi, while what you say is true as far as it goes, in detail things are more complicated than that. The L* is a sort of average of the human perceived response, in that what is seen as linear depends critically on the surround.
