Even with CD-4, the useful audio frequencies don't appear to be much over 15kHz from the samples I could find online. The CD seems to be technically superior in creating signals at the highest audible frequency range.
An old Popular Science article, just for fun:

The frequency response deviations do resemble a roller coaster tack with the carrier frequency measurements.
