May be it's my misunderstanding between those two rendering intents.
But Absolute colorimetric is clearly broken in MPC-HC. It produces a very
bluish gray gradient with some other artifacts.
(Hmm. The peak white is yellowish. If it would correct it on a stupid way,
then the other bluish grays should be even more bluish, so... I don't know.
But I made a quick test: I tried to use this intent on my desktop PC with a
different display, and the same thing happened - bluish distorted
grayscale...)
And I tried to use Absolute colorimetric when I converted the MS Paint saved
image into the device profile. I didn't work.
And I finally got a good result in PS when I used Relative colorimetric.
But I will check. (In the mean time I started to create a new profile from
2386 points and I also specified the equipped sRGB.icc for B2A table
creation.)
