But I don't think I'd be able to detect such intricate details. Do you additionally have "perfect pitch" btw? (absoluuttinen sävelkorva)

Yes, as the joke goes, there is no such thing as a piano which is in tune.
J.S. Bach wrote The Well-Tempered Clavier (although the title of that book was originally in German), but work on that topic had actually been going on for a few hundred years before Bach put the final touches on it. The tuning troubles began with the development of early musical instruments, which both individually and collectively could far exceed the range(s) of the human voice, and eventually Equal Temperament tuning (also known as "piano" tuning) was adopted as a compromise, without which there could be no such thing as an orchestra.
Music of the Baroque era sounds sweet, harmonically pure, and with thanks to Just Intonation, but that is contrary as to how a piano is tuned.
