While 192KHz is overkill, there are plenty of instruments that produce non-trivial amounts of energy above 22KHz. While we're unable to hear them some can be generally felt (depending on volume and proximity). A pair of headphones won't reproduce those ultrasonic energies but good speakers can. Even so, this is only germane in a handful of types of music with high fidelity recording and mastering.
The same for higher resolution samples, an audio pipeline using that available dynamic range can do cool stuff.
Both are pointless for 99% of music sold though.
