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.
