Ok.

Yes, I had to read many articles about the difference between monitor 
calibration and profiling (and how many people new to CMS confuse both).

I see. I get it now. And indeed I notice a BIG difference on my overall desktop 
when I load the ICC profile.  The change on visual appearance of my screen - 
when the calibration-part gets loaded (gamma & white-point correction) - is 
considerably higher than the changes made when a color-managed app takes into 
consideration the profile part (color correction).

I see, so the GNOME desktop (and practically anything X-related) takes 
advantage of the information stored on  the VideoLUT but I won't see anything 
color-corrected (from the profiling part of the ICC) until a capable app is 
configured to do so.

Thank you very much Pascal !   I really appreciate your help.

All the best,
