AFAIK, Shield only supports single layer DV profiles, that is profile 5  and 8. So it seems like getting it to play DV 7 at the moment is moot.

But then how come that the profile 7 MKVs trigger DV on our TVs and seem to have the correct colors? Or are you saying that this is some kind of "fake" DV where we are actually looking at HDR10 video without the DV metadata?

I believe DV is working. I also have an E6, hooked up through an Onkyo RZ820, and ALL P7 mkvs work with the first matrix builds from here. I am also positive that DV works, as i see differences (especially noticable with SPR, which is "buggy" on the shield in DV, no matter which player (exoplayer+plex+kodi), with some annyoing "flashing" in scenes with a lot of white, very easy to spot in the first few minutes with the flags against the sky.
