Nowadays, I'm not sure exactly what it is I'm buying when I buy the
"dipped mica" caps. I'm confident to say they are better than the
old-timers but are they silver plated onto mica or what?

They are plated, but I don't know for sure that there is any sliver in
the process. Perhaps there never was....

I share your confidence, but only time will tell for sure.

Mica used to be cleaved and plated then a lower costt mica reconstituted
was employed all were silver evaporated.
Dipped refers to the encapsulation.
Low values had their tc altered by the encapsulation material.
Modern npo ceramic chips are Much? Better. Also some porcelain are the
best for Q ie loss.
