Sorry if this is an stupid question :-p
What about display filters/soft proofing/whatever you call display 
correction?
When/where it happens?
There is an interesting section about that here: 
http://cinematiccolor.com/ (page 29 of the document)
I'm not sure if this is too focused on motion-picture work, but the 
whole document looks very interesting anyway.

Is any of this appliable to GIMP?
