I'm not seeing anything out of the ordinary. ffprobe shows that chroma location on episode 1 MKV is set to left just like the original M2TS, which is correct for Blu-ray.

The authoring company forgot to shift the chroma when converting to 4:2:0 subsampling which results in a center chroma location.
The BDMV's left-aligned chroma is wrong due to this.
The chroma location tag can be fixed losslessly with ffmpeg's bitstream filters but the remuxer didn't bother.

I see what you mean after splitting a screenshot to YCbCr components in GIMP. Chroma location looks correct after doing the fix with ffmpeg bitstream filter.

after splitting a screenshot to YCbCr components in GIMP.

This is the most scuffed way possible of checking but whatever works I guess

Can anyone provide the proper ffmpeg command line to change the chroma_sample_position?

Something like this should do:

ffmpeg -i "input.mkv" -c copy -map 0 -bsf:v h264_metadata=chroma_sample_loc_type=1 "output.mkv"

@Aergia the wrong "chroma location set" what problem can cause? When played the colors seem fine to me.
Can it cause problems during ancoding?
