What's the status of Dolby Vision + Atmos on Plex? (re: LG WebOS, Nvidia Shield, Apple TV)

I have a SHIELD 2019 and a LG CX OLED TV.

I can play single track dual layer Dolby Vision without issue.

I rip my BD with MakeMKV and MakeMKV muxes the 2 tracks into a single track (dual layer)
DV info: dvhe.07.06 BL+FEL+RPU (That’s DOVI Profile 7, DOVI level 6)

All the BD’s I have ripped has had either dvhe.07.06 BL+FEL+RPU or dvhe.07.06 BL+MEL+RPU

Plex play the files just fine and triggers Dolby Vision.

The only issue I have had is that TrueHD Atmos will often clip or dropout, making the atmos logo appear in the corner of the screen over and over again. If I playback with DTS-HD or Lossy Audio, there is no issue.

Plex server on a NUC, media on a synology NAS, gigabit network.

NOTES:
Make sure instant game responce is enabled on LG CX or Dolby Vision will not trigger.
LG HDMI Audio format must be “Bitstream”. If you switch to PCM Dolby Vision will not trigger.
