I have created icc profiles with colprof and the CC Passport target. The

find that the target white patch is rendered as 100% white (255 in stead of
244). What am I missing?

That target doesn't have very many patches, not enough, it seems to me, for a
LUT profile ("-qh -aX").
I wrote up some considerations about what kind of camera input profile to
make for various purposes (critiques are very welcome!):
Maybe try "-am", using the procedure in this article to fix the white point?
