I just tried to set the device pixel ratio to the page created with SVGImage (hard coded). The image looks indeed better initially. If you zoom in the page, CMD +, the pattern is slightly blurry again Nst much but if you look closer noticeable.

The real problem is that the image seems to get gigantic in memory size as more you zoom in causing the browser to crash at zoom level 200%.

Everything tested with the CSS Masking document. So simply setting the devicePixelRatio seems to be wrong.
