It's not exactly what you're asking about, but maybe related.
I'm recalling my experience when I was still low-vision with printed

scores. I was never able to get satisfactory magnification results. The

problem at the time was a matter of scaling, imho. The note heads (and

other elems, like the two bars indicating 16ths) were heavy and large

relative to fairly thin stave lines and note stems. So, if I magnified

enough to see the staves, the notes were heads were preposterously

large. On the other hand, if I made the noteheads comfortable to see, I

could not find the staff nor the note stems.
So, my guess that magnification of score would require a rescaling where

small elems receive more magnification than large, heavy ones.
Not sure if this helps at all.
