Kindles use a reflective display, so a gamma (light emission level vs signal level) value for a "linear" response (gamma=1) should be correct.
I.E: Since the display is "true grayscale" the hardware should be producing a linear response.

If you want to check up on the hardware designers, try this web-site with test graphics (*.gif): http://www.photoscientia.co.uk/Gamma.htm
