Equality works until we return from a surround profile to a non-surround profile. At this point the displays are reordered by windows, and the windows display configus don't match any more. Addtionally, it looks as though we need a 0.5 second pause between applying the configuration, and reading the new config. There appears to be a difference between HDR before we changed to the surround proile and after we've returned, and that's not a good thing!
The derived ProfilteItem classes were an unnecessary distraction and wasted time I could be spending on other things. This set of changes are the first part of removing those derived classes and moving to a single ProfilItem class again, but with different configuration slots within it. Makes equality comparison SO MUCH EASIER!
