Unless someone with expertise in optics can correct me, I'd assume that adding a uniform light source to any surface would result in a uniform reflectance across all regions. The blacks and the whites would both reflect 100% more light if you increased the front light by 100%. So I don't see how the front light would increase contrast as measured by a photometer.
Amazon's Kindle sales numbers are so full of smoke and mirrors that your skepticism over their technical specs doesn't surprise me. I tend to believe them for just one reason: when I see side-by-side photos of the Paperwhite and previous Kindles, 25% looks
accurate, if not conservative. It doesn't look like the PW will have the same contrast as paper. All I care about is that it's better than the Kindle line's traditional greyscale display.
