Getting a little off the original what is the difference between sRBG v1.31 (Canon)" and "sRGB IEC61966-2.1".
That is one view, however over the years there are certain industry standards such as AdobeRGB1998.icc suitable for the majority of purposes. A useful comparison here: https://www.cambridgeincolour.com/tutori...gb1998.htm
Send your photo off to a printer and they will probably ignore the embedded profile and use stock sRGB. I mentioned earlier that a commercial printer might specify a profile for use with a specific printer/paper. This a quote from my local printer
"These are the ICC Colour Profiles that have been specifically created for Digitalab’s Lightjet 5000 printer. These are for photographers with a knowledge of Colour Management and are by no means essential." - note no means essential.
Any number of icc profiles free to download if you search. I will start you off, top of the list http://www.color.org/profiles2.xalter
Gimp 2.8 will change the profile Image -> Mode -> Assign -> Colour Profile. As a note Gimp 2.9 can extract a profile as something.icc Using Windows? Partha's Gimp 2.9 co-exists with Gimp 2.8 (using linux, there are portable versions of Gimp 2.9 that might work depending on distro)
Going back to your first post "the differences on my display which is a moderately good (27" 1920x1080) one (but has not been calibrated) are imperceptible."
There is information here: https://www.cambridgeincolour.com/color-...inting.htm where even an adjustment in monitor brightness can get a better match between what you see and what you print.
Your posts do read like you should really be asking advice on a more photographic biased forum, such as https://discuss.pixls.us/
Quote:The idea of exporting an ICC profile from a source/input file and then importing that profile back into image files exported from GIMP would suggest to me that what GIMP calls “converting the working space" ought be avoided.

Quote:In the event that GIMP is allowed to perform this conversion, which includes essentially all of my work prior to now, is it possible to find something to import in those cases?
