I have an icc profile for my monitor (created by ArgyllCMS 1.0.3b). When I try to load it by means of dispwin (but the same applies to xcalib) the profile is loaded without any error message (and dispwin -V confirms that the LUT is correctly loaded), but there are no visual changes on the screen.
Maybe your monitor's native color response is too good. Downgrade it to a worse one or mess with the adjustments and you should see a difference. :-)
Or you could just run dispcal -r to check the calibration.
