How can I create 3D visual comparisons of two icc profiles, on Linux?

Wondering if anyone can help me with this:

I’m looking for a way to compare any two icc profiles as 3D models, as illustrated in the attached image.
The closest I’ve been able to come so far is comparing a display profile created in DisplayCal with another profile which is included in the ICC Profile Info part of the program. I can’t see a way to load two profiles from disk though.

Any help appreciated!
