If that's the case, it's good enough for our immediate needs. Then we 
just get the ICC profile for the main screen, and use LittleCMS to 
transform from our internal format to the proper colors for the 
display. I was worried that the output was locked to sRGB on OS X (like 
the situation with GTK) so you couldn't make full use of wide gamut 
screens which would be very limiting for our application.

As most users with a color-managed setup have one primary screen which 
they do all color-critical work on it's not too bad to only be able to 
present correct colors on that.
