That 1920x1080 'HDR' layer is the Dolby Vision Metadata. I don't know why folks say MKV doesn't support a separate DV track alongside the HDR track. I've taken a full disk rip (of my legally purchased Valerian UHD), and used MKVtoolnix to mux the HDR and DV tracks from the main .M2TS file together into a single MKV file. Of course I've got nothing to play it back with, but the MKV container holds it just fine. Once someone figures out how to combine the two video tracks into a single video stream, we'll get our DV playback.
You can 'play' the DV layer in VLC, by selecting the second Video track. It looks about as you would expect with funked up colors, but you can see it clearly resembles the HDR track, just at lower resolution, with funked up colors.

It's a closed, proprietary format and no way to store it in MKV.
Today I saw a "release" of a movie that was MKV and had 2 video streams. I assume the second is the Dolby Vision layer.
MediaInfo:
Is it now possible for MKV to have the DV-layer? I can't seem to find any information on the Internet regarding this, I'm no expert though. I have the file and when selecting the second video track the video just stays black in MPC-HC with madVR, just like with the UHD-BD ts-files.
