--- Comment #10 from G Seifert <gs at schriftgestaltung.de> ---
I indeed had activated lossy magnification with PNG quality set to 80%. 

I checked some files and for some the difference was very little (only a few
pixels changed a tiny bit), but for others, it would introduce dithering that
was clearly visible in magnification
(Inkscape.app/Contents/Resources/share/icons/Adwaita/256x256/legacy/face-angel.png).
Those were also the ones with the biggest savings. 

I don't know where those icons will be used but a 125kB for
Inkscape.app/Contents/Resources/share/icons/Adwaita/512x512/legacy/accessories-dictionary.png??
(this one compressed very nicely to 55 kB).

So just running it through ImagOptim will not work but seeing that icons can be
better compressed and checking what icons are actually useful at what
resolutions could save quite a bit.
