I would say 8 out of 10 as it looks to have had normal use. The majority of the marks can't be seen unless you tilt the screen one way or another.
If you installed tempered glass on this screen, I would say the marks / scratches on this screen would be covered and not seen at all. I see one line scratch that can be seen without tilting the screen from side to side which is located in the bottom middle area. As you can see in photo #2, the touch is working on this screen. Please take very good care when installing this screen as the touch cable can be very delicate. If you have never done this repair in the past, it may not be a good idea.
I did my best to get photos of the screen but it is very difficult to photo a screen. The item "Original OEM Apple iPhone 11 Pro Max LCD Screen Digitizer Replacement Good" is in sale since Monday, September 27, 2021.
