I've cleaned a lot of them, but never for the sole
purpose of seeing if it affects picture quality.
It does not.

Sure it does. The collection of dust, and much of that moistened at
some point makes for a leaky anode supply and feed wire at the very
least. That makes for poor or shifted focus settings, and other
problems that less than your average video afficianado won't notice.

I (semi)regularly clean the insides of my desktop computers. Opening
up, reseating all boards and connectors is a good thing, IMO. In fact,
this particular computer had started having 'symptoms' a month or two ago.

I performed the above, and everything was set right again. There was a
lot of dust on the fans and quite a bit had caked up inside the power
supply (yes, I even opened up the ps).

I won't wait so long the next time....

But, no; to answer your question, I rarely clean the inside of my
monitors (unless I have to get inside to address some issue).

Most folks rarely notice their focus shifting as well. One has to be
video oriented to notice such things.

This is why I bought the one monitor in the world I could find that
has the highest video bandwidth out there at 185Mhz (now the *******s
are up to 210MHz!). Nice, tight, crisp and clean, CRTs are STILL the
king!

Just to back the pro cleaning side, when I made my living from servicing
monitors (and before that TVs) every once in a while I'd get one on the
bench with the safety shutdown tripping because of a buildup of crap around
the anode connector or other HV parts, but then I've also had nearly as many
repairs in that people had damaged cleaning the inside when they didn't know
what they were doing!
