dvhe.05.06 file to UHD disc? Is this even possible

[JovianResolution]

I have a 31 GB 4K Dolby Vision Profile 5 copy of a movie which I am trying to burn (keeping UHD) onto a BD-50.
Also, it is cropped (the movie is in 2.39:1 aspect ratio)
My usual set of tools is not working and a lot of this seems extraordinarily complicated.

Attempting to make a burnable folder using the original file with TsMuxer results in:
Dolby Vision Double Layer Single Tracks are not standard for BD disks, the disk will not play in a Blu-ray player.

I first tried to add horizontal bars with ffmpeg and it kept giving me the skewed colors.

My understanding:
Profile 5 gives DV only and will show up skewed (greens/purples) on non-supportive devices
Profile 7 is what commercial UHD discs use (contains both HDR10 and DV)
Profile 8 also contains both HDR10 and DV

From my reading it looks like there is a way to get from Profile 5/7 to 8 but not vice versa.
Using: https://forums.plex.tv/t/dolby-video-profile-5-to-8-1-mkv-conversion-script-get-rid-of...-purple/936976
I was able to convert the file from Profile 5 to Profile 8 but TsMuxer gives me the same error.

I then tried to re-encode to get rid of the Dolby Vision entirely and just keep the HDR10 (as my 4K Blu-ray player only outputs HDR10) using:
https://forum.jellyfin.org/t-converting-dolby-vision-to-hdr10

But when I open the resulting file in MediaInfo it tells me that it doesn't have HDR at all. (but it is Main 10@L5@High with BT2020). I try making the Blu-ray folder with TSMuxer and it doesn't give any errors. When I open the resulting mux in MediaInfo, Color range is marked as "Limited"

Could it be that the HDR is still there and there is just an issue with the metadata?
Also, would having a cropped file (3840x1608) make it incompatible with UHD Blu-ray players?

I ran the second command and it fixed the metadata. What I'm not sure of, however, is if the 2.39x1 file will play normally. Will I have to encode the file a *third* time in order to add the top and bottom black bars?

Edit: At Step 4 in the first link file (5 to 8.1 converter) I added:
'-vf', 'hwupload,libplacebo=colorspace=bt2020nc:color_pri maries=bt2020:color_trc=smpte2084:format=yuv420p10 le,hwdownload,format=yuv420p10le,pad=3840:2160ow-iw)/2oh-ih)/2:color=black,setsar=1',

Which adds the black bars making it a regular 3840x2160 file. Then after that's re-encoded and the Dolby Vision stripped, I run the metadata app to fix the metadata. Once TSMuxer puts in a Blu-ray folder format, I right click the main video file with MediaInfo, and the HDR is....gone.
