However, it doesn't possible to load into LUT table from an .icc/.icm file and set _ICC_PROFILE atom using a single dispwin call. That would be nice to have.
It didn't seem like something someone would need to do: You set the _ICC_PROFILE atom after creating a profile. That happens occasionally. You've probably already loaded the calibration on your screen in order to evaluate it before deciding to overwrite the _ICC_PROFILE atom. You set the display to the _ICC_PROFILE atom every time you start the system (or even more often). Besides, the UNIX philosophy is to make one tool per task, and then combine them, and it complicates the specification and interpretation of the specification to try and combine these two tasks in dispwin, without changing its operation in an incompatible way.
In the documentation, there is a small error in dispcal for -o option : "If the -o flag is used, dispcal will also create a shaper/matrix profile, if the -o option is used"
Thanks, Graeme Gill.
