Pascal explained to me that for internal colour matrices, DT does
the autoexposure, so only for private profiles, the "-u" is useful.

I think the yellowing is correct.  The question remains: Why does DT
behave different here?

It seemed poor to me because I checked a deeply blue patch.  Bad
idea.  The colour profiles -- my own, the Adobe profile, and the new
"enhanced matrix", are not far away from each other, and all three
are good.
