For a professional musician you are oddly singer/violin focused. Any instrument which can physically detune while playing has their musicians do this. On wind instruments it's via the mouthpiece, any string instrument beyond violin has some flexibility etc. It's only the piano that doesn't, essentially everybody else does.

But in practise, for many music styles, it doesn't really matter. Music is so much more than whether some chord is pitch perfect in tune.
