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.
