The germaine issue here is that old geezers can‘t hear above 12 kHz if they are lucky to even get that far. Yet they can tell when a supertweeter with a 15kHz cutoff is present and the effects are wholly beneficial. Go figure what to measure for starters.
My take is simply that harmonic overtones, and CD does cover harmonics up to 22kHz, have a profound impact on the perception of the base notes, the exact nature of which requires measurements not yet invented.
To anybody prepared to listen carefully, supertweeters, and particularly on digital, are a must for advanced audiophile listening
