Did lcms2 change their built-in sRGB, compared to lcms1?
First variant (the good one):
argyll
canon (and possibly nikon, based on Iliah's xicclu numbers)
RGB XYZ primaries exactly/almost exactly equal to this:
0.43604 0.22244 0.01390 0.38510 0.71693 0.09708 0.14307 0.06062 0.71393
Second variant:
lcms website download: http://www.littlecms.com/1/downloads.htm
a twelve year old sRGB profile on a twelve year old Windows machine
showfoto
photivo
the two color.org V2 srgb profiles
Adobe icc profiles from Opensuse package
RGB XYZ primaries exactly equal to this:
0.43607 0.22249 0.01392 0.38515 0.71687 0.09708 0.14307 0.06061 0.71410
Third variant, farthest from Argyllcms, different from lcms1:
an openicc sRGB profile:
http://sourceforge.net/projects/openicc/files/OpenICC-Profiles/
darktable
ufraw
cinepaint
rawstudio
rawtherapee
krita
RGB XYZ primaries exactly or almost exactly equal to these:
0.43585 0.22238 0.01392 0.38533 0.71704 0.09714 0.14302 0.06059 0.71384
Where this third sRGB variant come from? Did lcms2 change the RGB XYZ
values for the built-in sRGB profile, compared to lcms1? Or is this
third variant strictly an openicc/oyranos variant?
