Like You mentioned in a further reply, it's more a problem to have a good profiler, which can make use of profiling hardware, like a spectrometer (e.g. eye one).
I think Hal V. Engel is on the way to improve the little-cms profiler 'lprof' which have not been developed for a long time, because Marti Maria (the developer of lcms) works now for Hewlett-Packard. Thank you for your work on lprof Hal! Just to make some things clearer. Kind regards Gerhard Gau?ling
