Why would you want to override one profile with another?

'Overriding' the profile set by dispwin could be a bad idea:
dispwin can install a profile that modifies the LUT for the graphicd card, 
which corrects all output to the graphics card from all applications. This can 
be completely transparent to the applications (as in, "they don't have to know 
what happens")
The profiles used by digikam are (I suppose) more like translation tables, 
where the program using the profile translates the image data before sending 
them to the graphics system. 

So, 'overriding' the profile set by dispwin could have one of two effects:
- the LUT profile is disabled, meaning that images from Digikam display 
correctly, and everything else will be uncorrected (not what the one 
installing the LUT profile wanted, presumably)

- the LUT profile is NOT disabled; then what should Digikam do? Knowing that 
both profiles correct assume an uncorrected display, applying the 'digikam' 
profile before the LUT profile would give wrong colours on the image, and 
correct colours everywhere else (not what the digikam user wants).

This assumes of course that both profiles do their job. If one of them is 
wrong, get rid of it...
