these graphs look broken. are you profiling developed raws? or jpgs? make
sure there are no other files in a new empty directory but your raws..
especially no xmp files. oh, and maybe make sure darktable has no output
profile override set in the export module when you close it before running
gen-profile. the script will use darktable-cli which might be confused by
that.
