Re: [csswg-drafts] [css-mediaqueries-5] Clarifications on [video-]dynamic-range MQs (#6793)

> Both video-dynamic-range and dynamic-range describe the screen. The video-dynamic-range proposal concerns a weird quirk of user agents implemented in TVs. Given limited system resources and a clear priority use case, these devices have a quirky implementation where video and non-video are rendered in distinct "planes", which amounts to distinct screens with distinct capabilities. 

Yes, exactly. In other words, for most devices, these will have the same value. Only for a TV with a high-res, HDR video buffer and a (lower res, non-HDR) "graphics overlay buffer" will they have different values.

So the specification needs to more clearly reflect that.
