VNC simply ships the raw pixels from a remote display to a window on 
the local display.

I am not aware of any VNC which does any color transformations at all. 
VNC servers do not attempt to normalize the color.  Clients do not 
know anything about the color characteristics of the exported display.
Color quality may be intentionally reduced in order to improve 
transfer performance.

I am on a few VNC development mailing lists and this is the first time 
I have heard color management mentioned as pertains to VNC.
