Well, I haven't really tried it with a real color calibrator, but I have heard from someone who has used that argyllcms stuff successfully. Should be pretty straightforward to use. I don't really know how it is related, but there is dispcalgui/dispcal that automatically put themselves in ~/.config/autostart and load color profiles. Also there is this relatively new colord stuff which gnome seems to support (I think only loading profiles)... VST... well, it's a "standard" but it uses compiled native code. What can you expect? There are some projects like festige/fsthost/dssi-vst that try to integrate with wine. When I tried it I got very mixed results but then I did not try with a realtime kernel and additionally I only tried it with the default priority of jackd run as user. I was told it would work much better on low latency systems. Ubuntu Studio is apparently still a thing, so there are probably an number of easy to setup distribution with this stuff enabled. But yes, the VST situation is bad.
