Recently, I replaced a friend's iPhone 7 Plus prior to the release of iOS 11. He broke the replacement aftermarket screen & he gave me the phone with iOS 11.0.1 on it! Replacement broken screen touch works fine & I've just replaced it again for another new aftermarket screen; everything works fine!
I have photos of the rear of the original Apple screen as well as the two replacements screens. All the chips have digits printed on them.

Edit: this is the chip on the replacement screens with the digits printed on them
