well you could just change the gamma in the framebuffer to 0.4545 and set the gamma of the sun and sky to 1... that might work.

No need to gamma correct bump maps as they don't feed info into any color channels. I think the problem on the underside is stemming from the ambient lighting, if whatever is beneath it is light colored then I can see that happening when it throws its color onto the balloon.
