Suppose I really enjoy the monitor profile Argyll did on my system. Do you have any tools to help test that, indeed, the custom LUT dispcal calculated is indeed resident in my video card at the time of working with images in, say, Photoshop?
Do a screen grab of a 0-255 rgb ramp. Then use Photoshop to compare it with a similar screen grab taken when the LUT was known to have been installed.
