I just picked up a crimson DS lite, and I've noticed that the bottom touch screen is slightly dimmer than the top screen. For instance, at the start-up menu, the top screen is starch white and the bottom screen is more like a flat white. And at the Zelda start-up screen, the blues of the sky are more vivid than the blues of the water, and the foam of the sea is more a cream color than white in the bottom screen as well. Is this normal, or are both screens supposed to be equally bright? Sorry if I sound vague.
