this could be made more concise by using the suffix notation, i.e.

histogram ColorManagement.ColorProfileStatus
with suffixes JPEG, PNG, etc. Can see examples of suffixes in this file.

This makes it easier to add new histograms as well with much less boilerplate.

these should be seperate lines (i.e. seperate owner tag per)
