Hmm, well, double-checking, I used GIMP-2.8.22 to open a jpeg with a from-disk V4 sRGB profile embedded (the same profile you are using), and in “Images/Properties” on the “Color Profile” tab, the profile description (which for my profiles matches the profile file name) is shown.
Perhaps this is an issue with the Mac version of GIMP-2.8?
In the Mac version of GIMP-2.8, does the image as exported by GIMP-2.8 still have the embedded ICC profile (open and then immediately export under a new file name, and check to see if the profile is still embedded). Checking on my copy of 2.8.22, the profile is still embedded.
At any rate, I’d suggest asking on the GIMP developer’s website if the Mac and Linux versions differ in how profile information is displayed, and/or in how embedded profiles are treated. If yes, then this might be a bug in the Mac version.
