Yes, that's what I meant!

This I do not see (even with careful look). At least, following lines
give me pixel-level and smooth scrolling. Not for you?
(dotimes (ii 10)
(vertical-motion 1)
(dolist (vs (number-sequence 1 (1- (frame-char-height))))
(set-window-vscroll nil vs t) (sit-for 0.02))
(scroll-up 1) (sit-for 0.02))

Let's say the lines above give smooth scrolling. If so, to make Emacs
scroll both up and down with pixel-to-pixel resolution, requirement is
that `set-window-vscroll' accepts negative number.
