The brilliance keyword controls the falloff rate of the shading, and has 
nothing to do with the diffuse value, and reflection depends on the 
surroundings, whether or not to change it depends on your goal.
I'm not really sure what you're trying to do...I thought your problems 
were with overall contrast, but your message implies either you are 
trying to adjust individual objects or that you misunderstood my 
message. Did you try my suggestion of using no ambient light? My message 
didn't mention changing diffuse at all.
