I would. It’s really simple.

The human threshold-of-hearing curve intersects the threshold-of-pain curve at about 20 kHz.

Above that frequency (or thereabouts) the sound has to be so loud that it will literally instantly damage your hearing before you can hear it.

This has been replicated across many studies for more than 100 years.

Flicker threshold is completely different. You can’t damage your vision by increasing the FPS, and it has always been commercially desirable to use a lower frequency because that is cheaper.

Would you agree that a trained human could identify artifacts produced by an imperect conversion process? If you lean "yes", then that's your answer: AD/DA is not a Rust function perfectly implementing the Nyquist theorem, it's a collection of physical components many of which introduce artifacts into the audio path. This thread is not about the theory of human hearing, the electronic components are literally imperfect.
