This seems to be a result of autobrightness. If autobrightness is disabled then the brightness changes immediately, but with autobrightness enabled it's probably waiting until it gets some ambient light data to determine what brightness to use. I guess the best option might be to save off the brightness before dimming the screen and then restore it when undimming.
