tested on MacBookPro 13" M1 on Ventura 13 with an external Display. Ha Gotcha. It looks blurry on the Retina screen on the MacBook Pro but not on the external display.

Did some additional checking and it seems to be related. Considering that blurriness can be reproduced only if SVG is used as <img/> src input.
