I have not been able to get my mkv file to provide Dolby Vision and Atmos to my TV and Receiver.
So I backed up the entire 4k Blu ray as folders with all the streams in the BDMV folder
I was able to play the stream file .m2ts file direct from my Sony UBPX800M2 with connected SSD drive (NTFS) into my A80J tv and Atmos on my Onkyo tx-nr797.
Dolby Vision displays on my TV and Atmos on my receiver.

If anyone has gotten the mkv file to perform the same please let me know. Thank you

you have to find out if your TV/receiver support DV in a MKV container.

I have a LG C1 and it only supports DV through a MP4 container.

If it's an mkv specific issue, then it's nothing to do with the TV or receiver. Matroska doesn't get sent over HDMI. It's your playback device/software which has to understand DV in mkv. The receiver and TV do both need to support DV and DA though, of course.

I find that converting dolby vision metadata to Profile 8 (Single channel, dual layer, HDR10 compatible) produces the best results.
