Edited: Problem is this link. I’ve tested with https://www.udemy.com and it gets fine, but when I add link to my courses it gets low quality. Tested in Safari and there it does not matter if add something to link, it stays the same.
Tried to Empty Cache Orion re-download new icon, but anyway with low quality.
