PG vs HLG is important for the *can this be rendered* question (which is answered by `decodeInfo()` but not for the *should I choose this one* (when I have a choice).

Good luck with that ;-) The question I want to answer is whether it would produce a better result to send HDR content vs SDR when I have both available and the device can render both. At least at the margins this is a matter of opinion. So then I think we should leave this to UAs, as agents of the user, who is the one with the opinion.
