I confirm that generally XYZ-LUT profiles are tend to significant banding in

The banding is preventing the use of -ax key for display or camera profiling. 
The

with
latest versions). IMHO, much more smoothing is needed for XYZ data in the 
darks, may be
in overall.


How are you testing this ?

Can you reproduce the problem using imdi/cctiff ?
(ie. are you sure it's not a CMM issue ?)
