Regarding my findings here (https://discuss.pixls.us/t/how-to-add-camera-support-to-libraw-darktable/44774 (https://discuss.pixls.us/t/how-to-add-camera-support-to-libraw-darktable/44774)) the necessary information for exiftool should be:
0x80000496 => 'R5 Mark II',
I don't know how the ColorData is versioned, so I left it at 11, could as well be 12.
{ (int16u[4528]) - R5m2
Condition => '$count == 4528',
Name => 'ColorData11',
SubDirectory => { TagTable => 'Image::ExifTool::Canon::ColorData11' },
},
PrintConv => {
34 => '34 (R3)', #IB
48 => '48 (R7, R10, R6 Mark II)', #IB
64 => '64 (R5m2/R1)',
},
I don't know if this is all, just wanted to get the discussion started. Samples, if needed, can be found here:

Thanks. I'll look into this when I get a chance.
You don't mention the R1, but you have ColorDataVersion 64 as "R5m2/R1", so this also applies to the EOS R1?

According to the raw files from https://www.dpreview.com/sample-galleries/3304843825/canon-eos-r1-pre-production-sample-gallery/2560995570 (https://www.dpreview.com/sample-galleries/3304843825/canon-eos-r1-pre-production-sample-gallery/2560995570) it seems to be 64 there as well
Thanks! I'll add the CanonModelID for the R1 as well.

I spent some time to look at this now. There are changes since ColorData11, so this will be a new ColorData12 structure. Here are the new offsets:

I'm sure this is not complete, so let me know if you discover the meanings of any unknown tags.

Thanks, this helped a lot. As I'm a exiftool/fileformat noob mind guiding me to a place where I can read about how to identify those tags you identified? I mean the numbers are a small hint but when I extracted values some weeks ago using "-a -U -H -v4 -b" as mentioned on https://github.com/lclevy/canon_cr3 I can't think of a way to definitely say this is Daylight or this is asShot. So I must certainly lack some information next to experience.
AsShot was a guess based on the fact that it usually comes first. To be sure about this you would have to change the camera white balance through a few settings and see how this changes. The others I based on the ColorTemperature, which gives a good indication of which white balance setting it is for.

Thanks :)
