Raw Histogram, or Display Histogram

@afre There are quite a few ways to extract information from an ICC profile in human-readable form (even including using a hex editor). Somewhere on this forum there is a thread that lists a lot of profile-related software. I think Rawpedia has a write-up.

The simplest way to turn a profile into something readable with a text editor is to use iccToXml:

SampleIcc Version 1.6.8, ICCXML Version 0.9.8
Usage: IccToXml src_icc_profile dest_xml_file
