Yes, same issue.
I just got my Shield TV pro some weeks ago, so besides Plex that works perfectly, I haven't tried anything else than Kodi Mavens Nexus betas and RCs.
Before that, I owned a Coreelec box (Beelinkg GT1 ultimate) for years and it worked without any issue with Dolby Atmos/true HD tracks, but it couldn't handle dolby vision.
For now, I'll stick with Plex which is the only reliable player for Dolby Vision/Atmos movies.
