Hi. Sorry to ask for help in my first post, but after trawling through this (awesome and very long) thread, I haven't been able to find steps that work for me…

Is there any way to convert a STDL MKV file with Dolby Vision into something the LG C8 will play with Dolby Vision? I looked at the test files shared here previously, and "DTDL_FEL_1_021120.mp4" is the only file that will trigger DV on my LG C8.

Current situation
I have a set of MKVs that went from Game of Thrones Season 2 UHD disc → Ripped to BDMV → Converted to MKV with MakeMKV 1.15.3 (Mac, if that makes a difference).

Here's what I see in MediaInfo:

Problem
I have an LG C8 with an AppleTV. I've had zero luck producing MP4s that play in Dolby Vision, so I figured I'd at least archive the 8 season boxset as Dolby Vision MKVs, get the benefit of HDR10, and then figure out some way get DV MP4s working in future. But, when I watch these MKVs on my LG C8 through the AppleTV (Plex or Infuse) or built-in player (Plex or DNLA) everything is too dark and muted. Blacks are pure black, but the brightest details aren't particularly bright. Details in hair are lost in dark indoor scenes; bright outdoor scenes look "meh". It looks worse than Game of Thrones 1080p Bluray in SDR.

So now I'm trying (again) to get the DV MP4 workflow going, but all my MKVs are now STDL and I can't figure out how to even extract the DV stream into its own HEVC file.

Is there any way to salvage these DV MKV files or am I stuck re-ripping everything?

I'm also wondering, is it normal for HDR10 rips to look dull? All of the Dolby Vision and even HDR10 movies I've bought through iTunes look great by comparison. I want the higher bitrate of UHD discs, but I've no space around the TV to have a disc-based player or a Shield. And there's nowhere to buy streaming 4K GoT on this side of the pond.

I hope you still have the ripped BDMVs laying around because your best bet would be to follow the steps outlined in the first few pages of this thread with mp4muxer to create DV mp4s for playback via your TV's internal player. Starting with the mkv is theoretically possible (multiple steps of hevc extraction + demuxing), but the effort needed may not be worth the trouble, especially if you have the BDMVs still saved.
