The manual recommends using assumed_gamma 1 for new scenes.

Pure white pigment, pure white light source, a diffuse of 1 and a 
brilliance of 0...there must be something else in the scene that makes 
it give this result. Could you post a minimal scene demonstrating this?

Light values above 1 are perfectly acceptable. Even negative values are 
allowed, though they don't correspond to any real-world effect. Pigment 
values above 1 (or even equal to 1) aren't realistic, but they are 
allowed.
