    Okay.  Would it then suffice to pick an arbitrary frame on the display
    given as the argument of `display-mm-width' and check the parameter of
    that frame?  That could be done with something like

    (let ((frame-list (frames-on-display-list display)))
      (when frame-list
	(frame-parameter (car frame-list) 'display-mm-width)))

    assuming the frame parameter is called `display-mm-width'.

That would work, if whatever sets that parameter sets it for
all the frames on the display.
