I saw someone commenting about a specific title (UHD/4K disc):

++++++++++++
"There are 2 video streams on the disc and Paramount uses FEL DV, so there's additional higher secondary bitrate, as well as 12-bit color resolution. Something not in the MKV"
++++++++++++

The poster seems to suggest something is missing (or not properly informed) in the lossless MKV that was created. Probably due to his ignorance to know these are ripped.

As far as I know, MAKEMKV can rip everything any UHD disc offers, so (correct me if I am wrong), in this case the Dolby Vision also has this "FEL" 12-bit layer, created into a single video stream. Is this true?

Yes. The issue is that almost no device supports it completely in that form.

Correct. He's probably familiar with the dual layer Dolby Vision files with the secondary metadata only stream, so that he's probably thinking that it's missing while this is a completely different Dolby Vision profile.

Correct.

Eh, that's the thing, unfortunately almost every device (including mine) will just ignore it and will read the 10bit base layer instead... :(

EL is there, so false.
