Reading your replies.

I've done some more testing, and I have to take back my assumption that the shield doesn't support profile 7 and produces "fake" Dolby Vision.
According to the logs it doesn't support it, but it seems no matter which profile the stream is, the DV metadata is being used.

@quietvoid : That means your point regarding strict HDR10 fallback and devices not reporting all their capabilities is valid.
I also agree that the focus should be on profile 7(if it matters) since this applies to most content.

Sorry for creating confusion.

BTW - I tested this by combining a base layer from one clip with an enhancement layer from another. It's then really noticable when the DV metadata is being processed. When using VLC which doesn't support DV, the combined clip plays back as normal HDR and looks correct.
