I don't know how to translate those facts into an interpretation of the
spectrum analysis noise charts provided in the OP though.

Googling, I can make a guess that my transient noise (blue line) is very
high at channel 10 of -40dBm, but that my average noise (green line) is
very very low at -90dBm.

The receiver sensitivity that someone asked me to look up is at about
my average noise level, at -90dBm ± 2dB for 802.11n signals.

So, the question I ask, without having the experience to know what "good"
transient noise and average noise levels are, is whether or not these
numbers are "good" or "average" or "bad"?

Also, I have no experience whether a peak instantaneous noise of -40dBm
(which is admittedly high) has any detrimental effect on my radio
performance (even as the average seems very low, at -90dBm).

I just don't know. Do you?
