nope, gamma describes the gain curvature over the input range,
colour tremperature is related to white balance.

(gamma can be applied equally to monochrome monitors...)

Macintosh monitors use gamma 1 which mean a linear gain - a signal input
half-way between the white and black signals prioduces a gray that's got
half the luminous intensity of the white.

PC monitors with gamma near 2 use a logaruthmic gain... (that's about all I
know)
