What you describe is what would happen if HDR were implemented and supported.
The way HDR is implemented though is not through a literal brightening of the pixels, but by bleeding the color into adjacent pixels - to give the sort of washed out effect you get from a camera which is getting excessive lighting (for example, pointing a camera at the sun). But that's not the effect that I am getting here - are you getting that?
