Hi all. GNOME Color Manager used to call colprof with -as, i.e. shaper and matrix, but Pascal changed that recently to -aS to keep the grey-scale neutral.
If the display is calibrated, then I'd also tend to use -aS or -aG.
Is there ever an instance where the user would want to create a cLUT (or either type) or any other type for _display_ calibration? Is there a way of working out when a LUT is a good idea automatically?
Well, depends of course on the "goodness" criterion of your choice. If the criterion is "accuracy", then I'd run some kind of cross validation. It is expensive though to build N profiles of each type from subsets of the whole measurement data (where N is say 10 or maybe even more), so this may stress the user's patience...
