Overwriting ULYOs color matrix&transfer from bt470bg to bt709 worked fine here.
-> share a debug output of it and I can look at it after work.

This is strange... I can confirm that ULYO and "advanced signaling" matrix+primaries+transfer bt.709 works fine.
MediaInfo:
Color primaries : BT.709
Transfer characteristics : BT.709
Matrix coefficients : BT.709
ffprobe:
yuv420p(tv, bt470bg/bt709/bt709)
However, ULYO and "advanced signaling" matrix+primaries SMPTE 170M and transfer bt.709 does not work:
MediaInfo:
Color primaries : BT.601 NTSC
Transfer characteristics : BT.709
Matrix coefficients : BT.601 // <-- this should be "NTSC", otherwise it is BT.470BG
ffprobe:
yuv420p(tv, bt470bg/smpte170m/bt709) // <-- as noted above, matrix becomes PAL, but we want it to be NTSC like the primaries
Please try this scenario and let me know if you can repro. If not, I promise I will send debug logs immediately.
Thanks!

SMTPE 240M primaries are functionally equivalent to BT.601 NTSC (SMTPE 170M) primaries, but they are still different indexes in the H.273 coding (6 vs. 7).
Check https://www.itu.int/rec/T-REC-H.273/en page 5. MKV supports both ( https://mkvtoolnix.download/doc/mkvmerge.html) so I don't see a reason it would get changed.
SMTPE 240M matrix and BT.470 System B/G matrix are completely different however, and this is the big problem.
SMTPE 240M matrix:
KR = 0.212; KB = 0.087
BT.470 System B/G matrix:
KR = 0.299; KB = 0.114
The same thing happens if you use SMTPE 170M as matrix (the BT.601 NTSC standard). It gets converted to BT.470 System B/G (the BT.601 PAL standard).
Source: https://www.itu.int/rec/T-REC-H.273/en
Also, may I recommend using ffprobe for this instead of MediaInfo since the former gives the actual codename of the color profile, versus the generic name of the latter (bt.601, bt.601 ntsc, bt.601 pal, etc.)

My point is, that from what I see Hybrid does the flagging correctly or do you see a mistake in the mkvmerge command line and/or the resulting output?
Looking at https://mkvtoolnix.download/doc/mkvmerge.html:
Matrix:
--color-matrix-coefficients TID:n
Sets the matrix coefficients of the video used to derive luma and chroma values from red, green and blue color primaries. The parameter n is an integer rangeing from 0 and 10.
Valid values and their meaning are:

this->addListField(QString("mkvColorMatrix"), values.at(0), values, false);
(from Hybrid source code)
Transfer:
--color-transfer-characteristics TID:n
The transfer characteristics of the video.

this->addListField(QString("mkvColorTransferCharacteristics"), values.at(0), values, false);
(from Hybrid source code)
Primaries:
--color-primaries TID:n
Sets the color primaries of the video.
Valid values and their meaning are:
0: reserved, 1: ITU-R BT.709, 2: unspecified, 3: reserved, 4: ITU-R BT.470M, 5: ITU-R BT.470BG, 6: SMPTE 170M, 7: SMPTE 240M, 8: FILM, 9: ITU-R BT.2020, 10: SMPTE ST 428-1, 22: JEDEC P22 phosphors
values.clear();

this->addListField(QString("mkvColourPrimaries"), values.at(0), values, false);
The flagging seems to match what Hybrid offers.

I think there's a misunderstanding here. I am not claiming that Hybrid incorrectly maps the color profiles to the appropriate mkvmerge index. The issue is that if you set "--colour-matrix-coefficients 0:6" (6=SMPTE 170M, BT.601 NTSC), either via "MKV advanced signaling" or via "customMkvmergeAddition", the output MKV file will have the matrix set to BT.470BG, which is "--colour-matrix-coefficients 0:5" (BT.601 PAL). Therefore, it is currently impossible to produce a final MKV file using UTVideo that will have the matrix set to BT.601 NTSC (SMPTE 170M).
If I run mkvmerge myself from Hybrid's directory like: "mkvmerge.exe -o fixed.mkv --colour-matrix-coefficients 0:6 bad.mkv", this time it actually works - the output MKV file has matrix set to BT.601 NTSC (SMPTE 170M). So the problem is not in mkvmerge or ffprobe/MediaInfo.
Random note: apparently mkvmerge uses "color" or "colour" based on your computer's regional settings, and since mine are set to UK... crazy

=> They both seem to be the same.

You are right! I don't know what I was doing yesterday when I thought that I could get ffprobe to show smpte170m as matrix, I think I may have accidentally ran it on an mp4 instead of mkv. Seems like ffmpeg assumes the matrix to be bt470bg only for UTVideo and doesn't care to look at the mkv signaling. No clue why MediaInfo shows "BT.601" instead of "BT.601 NTSC", but if mkvmerge itself can print the correct index, then the data must be correctly written. Sorry for the noise and appreciate your help as always!!
