When I say documented i'm mean the lesser meaning of this, i.e written down, there are no afficial documents detailing this, however the is a bug logged on MADVR here:
http://bugs.madshi.net/view.php?id=630
We moved the discussion about this to the driver thread as we had a complaint about spamming this thread:

This issue has dominated the last few pages of this thread, its now pretty clear the API is causing it, we're just waiting for AMD to fix it, here is DMU explanation of the issue:
You have entered support for HDR mode. The agsSetDisplayMode() function used to set a specific display in HDR mode, does its job perfectly: it sends metadata to the display device, which is defined in section 6.9 «Dynamic Range and Mastering InfoFrame» according to Table 5 of the CTA-861 standard. But in the same Table 5 there is also «Auxiliary Video Information (AVI)» defined in section 6.4. And all display devices are required to use the color space (colorimetry) from this data section (AVI InfoFrame) for the current video signal.
Suppose we are in SDR mode with the standard sRGB color space. And we want to switch to the HDR mode with the BT.2020 color space, which is the main one for this mode. By calling the agsSetDisplayMode() function, we put the display device in HDR mode. And we see distorted or unsaturated colors. This is because the display device did not receive the corresponding flag from the GPU in the AVI InfoFrame and is trying to display our BT.2020 color space in its sRGB.
Please tell me, do you think that such HDR support in AGS_SDK is sufficient? If yes, then advise what else needs to be done so that the display device passes into the correct color space when activating the HDR mode using AGS?
The outcome, MADVR is not sending BT2020 to your display so your colours are very unsaturated. Best workaround is to turn on windows HDR before starting your movie player.
