What is the purpose of audio mastering parametric equalizers having frequency options over 20 kHz?

In reality, most humans can only discern sound in the 20 Hz-20 kHz range.

Ignore these guys i.e. @Sadzandiuraye @Queen @Munyaradzi Mafaro

There are some audio mastering engineers who like to use wide bells e.g. with a quality factor of Q 0.404 (3 octaves) Q 0.305 (3 ⅔ octaves) at 24 kHz to add shimmer or air to a song instead of using either a 6 dB/8va or a 12 dB/8va filter shelving filter. Although that will be slightly similar to using a 6 dB/8va at 10 kHz.

For example, and just to be a little bit technical for interest's sake.

3 Octaves 12 dB/8va Peak Filter6 dB/8va Shelf Filter Equivalent
1 dB Gain @ 22 kHz1.25 dB Gain @ 9.5 kHz
1 dB Gain @ 24 kHz1.25 dB Gain @ 10...

To make the parametric equalizer look cool and more advanced than other basic mediocre EQs which probably do the same thing anyway except you can't boost anywhere above 20,000 cycles. 😁
