Windows provides a simple CMM and can load vcgt data to linearize a display. But there is no color management "from above". Color aware software explicitly uses the Windows CMM or an own solution (Adobe: ACE) to carry out color space transformations. To reproduce the background image in accordance with the current display characteristic you have to transform it into the display color space for example.windows is fully color managed.
There are solutions to create and apply CLUTs (based on source and target characteristics in the form of a quasi device link) to carry out color space transformations for videoplayback - but this is quite rare (MadVR video renderer is an example).newer media player are all color managed,
I don't know any game that would use the display profile to transform in device-dependent RGB. There may be games that can reload the vcgt linearization data from an accordant profile.good games are color managed.
No - you can only guess the target characteristic (unlike in the ICC workflow). But it's valid to assume Rec.709/ sRGB for ordinary media. Please keep in mind that Rec.709 doesn't define the trc for reproduction. That makes sense because the playback conditons vary considerably (light-flooded room vs. dark cave). With a sRGB or Gamma 2.2 trc you should be fine in most cases.Is there really a way to know if material has been created/mastered in the sRGB colorspace?
Of course there are very different workflows. It could be conceivable - take is as educated guess as I'm related not to the film but graphic industry - to grade with respect to the characteristic of the forthcoming the film print (a wide gamut display is important here). For the broadcast/ consumer media exploitation there could be a predefined (appropriate CLUT which ensures the desired intent) transformation to Rec.709 or a new grading process or hybrid forms. "Pure" Rec.709 workflows will also exist (non cinema).Odds are they are originally shot and mastered for something wider than sRGB would be my guess....and for the DVD release you get remastered/post-processed a bit. So your "faithful" sRGB panel may not actually be faithful at all-or it might be, no one person really knows-even the people who's names scroll in the credits.
Simply reproducing this material on a wide gamut (undefined) screen is no good idea. Sony implements some kind of optional gamut mapping inversion in their Triluminos TVs. This heuristic approach can lead to quite pleasing results (important midtones are shifted only slightly) - although it remains a matter of taste. But when thinking of a grading workflow like the first one mentioned above with colorimetric transformation to Rec.709 (=> clipping of out-of-gamut colors, precise transformation of in-gamut colors) - that means no source color space compression - it will necessarily degrade the result.
