(See Pictures of this screen to get an idea of the marks). I would say if you installed tempered glass on this screen, it would hide all of the marks on this screen and this screen would look brand new. 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.
