I'm not sure I'd go so far as to say "destroyed". Compare the text in this cartouche: https://imgur.com/7fGJg4s,iWf4pXG

At worst it seems comparable to the previous result. At least to my eyes.

For example, 4th character, two lines were converted into a stain.

Great point. FWIW, I've updated the post to include some of the cartouches, along with a cartouche at the "low noise reduction" level. The two lines in the fourth character appear to still be relatively distinct in this case.

That being said, I don't want by any means to disrespect the work, because it's clearly impressive.
