Yes, it indeed very much looks that way. Your examples show dots
(above) in horizontal text, and commas (or comma-like shapes) (on the
right) in vertical text, and some text in the scans actually say
that this is current practice.

From a purely aesthetic point of view, I'd guess yes. For a very
light font, smaller dots/commas may be more appropriate. For a very
heavy font, bigger dots/commas may be more appropriate. There may also
be issues with how far a way from the main line the marks go; for
different fonts, the optically best distance may be different.
But from a practical viewpoint, it is very well possible that such
adjustments are not done.
I suggest you look at some fonts, or contact some font providers
(e.g. Adobe and others).
Being able to specify a specific character as an emphasis mark
sounds attractive, but it would bring up the need to specify
several other parameters, such as scaling and offsets.
