May be, I have overseen it!
Is there no video converting function to convert 4k source format to a different 4k format?
-
I've never seen that in Media Center, but it has so many features that I may have missed it.
MKVToolsNix is what I use to do exactly what you want to do.

mkvtoolnix should handle it.
What's the 'source' for the .ts file?
Typically you'd be pulling .m2ts files off of a UHD BDMV.
.ts files are primarily from broadcast television.

:-XThanks for the response. There are files in my Lib of a few 1000 video files which don't have BitDepth and SampleRate. I know perfection :).
These are all demo files:
LG NASA HDR Demo.mp4
LG La Bohéme UHD.mp4
LG Chess HDR.mp4
UHD PQ Iceland 2.ts
I tested Handbrake for one of the files and after conversion BitDepth and SampleRate are there.

Cool
ffmpeg should handle this fine
ffmpeg -i input.ts -c:v copy -c:a copy output.mkv

I've been working on adding a couple of presets to MC's video conversion to do 4k H264 MKV and 4k H265 MKV.
Open to suggestions of the preset values from ffmpeg experts.
For H264 I've been testing
profile=high,preset=superfast,crf=23 and aac at 224kbps

H264 is starting to get rather inefficient at 4K. Especially if you need to run an even faster preset.
We don't currently have support for H265/HEVC encoding in place, and it'll naturally get even slower, so without hardware encoding "live" encoding is going to be troublesome quickly.
