I follow what you're suggesting but I'm not sure how to test the monitor for whitepoint change.  I believe NVIDIA's Detonator 3 driver actually does control gamma though.  Image is below.

| Easily tested ... if it brightens blackpoint,
| it is a brightness control ... if blackpoint doesn't
| change but whitepoint does, it is contrast ...
| if neither Bp or Wp change, it controls gamma
| (... altho you can wonder if it is a true gamma
| power function ...)
