Ok, I got my Shield connected and setup as best as I think with SPMC

Got a few issues, playing some 3D content (HSBS/HTAB) the display doesn't detect there is a 3D signal.
All sound formats seem to work, except Dolby Atmos ... it just falls back to TrueHD it seems.

Noticed that sometimes DTSHD isn't detected, restarting the movie doesn't seem to help, starting a movie with TrueHD and after that play the DTS-HD again ... it gets detected, kinda weird

With Netflix it seems that HDR isn't working, direct on the TV Marco Polo is detected as HDR and shows it right away ... on the Shield it just displays without HDR.

Any got some pointers where to look?

I got HDR working ... seems there was an update in the store ... that fixed it
Haven't found a solution for the rest though.
