Display colorsync profile remains unapplied?

[Roland Torres]

Just through observation. We have many custom profiles, some very  
distinctively "different" than the norm (for outdoor lighting  
conditions, etc.). So I ran tests setting the second monitor to such  
distinctive profiles, and after mirroring, there is no apparent  
change; it retains the distinctive setting. Are you seeing something  
that is different?
