In addition, harmonics are always presented as a lower frequency affecting a higher frequency, but never how higher frequencies affect lower frequencies. I'm saying these higher, inaudible frequencies affect lower frequencies. Can anyone shed light on that.
I'm not sure I understand the question. The character of what we hear is a function of the combination of fundamental frequencies, harmonics, and broadband spectral components that are present at any given time.
As Learsfool and I stated, seemingly credible studies have indicated that frequencies that are significantly above 20 kHz can be sensed under some circumstances, particularly if lower frequencies are simultaneously present.

When CD's came out, I bought them to hear the same music I had on LP, only better. One CD in particular was inferior to the LP, it lacked "nuance"; and as jazz lovers know "nuance" is everything.
I down loaded this LP to my computer, and on playback all the "nuance" was there; complete with record noise. What do you make of that?
Orpheus, an obvious question: What makes you assume that the CD and the LP were mastered identically?
Frogman, thanks very much the kind comment in your post of 1-26.
