How do you even measure those? Will that show up under something like VTune?

Yes, VTune is good.

I'm on AMD and uProf isn't that good (it often fails to match PDB to source, it's slow / crashy, stuff like that) so I mostly use Superluminal myself (has godly UX) and only drop down to uProf when I have a suspicion and want to gather hardware stats.

You can do all that with perf on Linux, but everything is manual.
