You have overridden the default value of display-mm-dimensions-alist,
but using an incorrect display name.  You should use "w32" instead.

In any case, you are not interested in absolute numerical values, just
in being able to distinguish between several different systems, right?
So the only thing that should be of interest is that each system
returns different values, no matter what those values are.

Like I said: use buffer-face-mode, it allows to set a font only for a
specific buffer, such as *Calendar* in your case.
