[argyllcms] Color errors on < 100% stimulus

I have a question regarding monitor profiling versus calibrating HomeTheater displays.


When I calibrate my Panasonic VT30 plasma (not connected to a PC) with an external program i.e ChromaPure I get dE errors in the range of 1.0 or less. The color calibration is done at 100% stimulus. But when I check the color balance at 75% stimulus I get errors of about 10 dE! Ouch! There is no way of correcting that in the TV set's controls even though it has a very thorough CMS module.

The question is when profiling a PC display with Argyll (or similar profiling software), does it correct color at different levels of stimulus or only at 100%? I.e if I would us my TV set as a PC monitor would the profile correct the color balance from 0-100% stimulus?
