Yeah there's an argyllcms package in Ubuntu too. So far however I haven't found an sRGB monitor profile that it can load without reporting some kind of error :(

I agree that this is outside the scope of Digikam, however it's a discussion topic that is only ever likely to come up on this kind of list. So how do we make it move outside this list and into the hands of the people who can solve it? This seems to me to be where the organisation around KDE ought to be able to make a difference. But can it?
