Double glazing glass defects

We recently had some new double glazing installed and had some issues with scratches. While checking over the other windows I found some marks like the picture attached on three of the windows. Are these marks acceptable or should I ask for replacements?

Yeah, I think that's where I am too. My wife thinks I'm mental, but I can't stop looking at the damn problem.
No change them, whoever fitted them will get them free from the glass supplier anyway if they are faulty.

Yeah I'd already seen the GGF guidelines. I'm just not sure whether these marks count as obstrusive. Now I know they're there, I can still see them if I stand 2m away. We're getting the small window with these marks on replaced as there's several of them, so I think you'd say they're bunched.
As the GGF guidelines say you need to look through the glass and not at it otherwise you will always look towards the mark, i bet if you asked a stranger to look through the glass they wouldn't see it, that said if i'd of fitted them i'd probably replace them out of goodwill and hope that MY supplier doesn't quote GGF guidelines to me in which case i'd be out of pocket
