I did as you suggested, and now the mystery deepens even more.
I cleared my calibration using xcalib.
I then did
eog test1 & (but note that the X atom was presumably still that from my
profile.) I then loaded your profile (which didn't have a vgct tag, so
it used linear) and ran eog test2, as you suggested. The results
differed radically. The colors were entirely different.
I then tried the following. I used dispwin -I sRGB.icm, and as in
your case, it reported that it didn't find a vgct tag and used linear.
I then did
eog test1.jpg &
I then did dispwin -I my_profile.icc, which loaded the calibration and
set the atom _ICC_PROFILE. Of course the test1 image changed because
the calibration changed, I then did
eog test2.jpg &
the test2 image was subtly different from the test1 image.
I then ran
inkscape test2 &
With the profile active it looked like eog test2 and with the profile
deactivated, it looked like the newer eog test1.
So I have to conclude that eog is using the profile information.
I don't know why I thought it wasn't before. I will have to go back and
check my previous experiments. Part of the problem may be that the
profile is making a relatively small change in comparison to the
calibration. If that is so, I could be misled when comparing images on
different parts of the screen. Or, it could be true that these
different applications are doing color management somewhat differently.
PS What is the simplest way to clear the Xatom _ICC_PROFILE?
