I've checked doc-view-revert-buffer. It works over
doc-view--buffer-file-name. So it doesn't detect a changed pdf, see its

--8<---------------cut here---------------start------------->8---
doc-view--buffer-file-name is a variable defined in ‘doc-view.el’.
Its value is "/tmp/docview1000/123.pdf"
Local in buffer 123.pdf</ssh:host:>; global value is nil

Only used internally.
The file name used for conversion.  Normally it’s the same as
‘buffer-file-name’, but for remote files, compressed files and
files inside an archive it is a temporary copy of
the (uncompressed, extracted) file residing in
--8<---------------cut here---------------end--------------->8---

Nothing Tramp could do. I recommend to write an Emacs bug.
