JerryRigEverything noticed scratches at levels 6 and 7 I highly doubt anyone in an apple store can do those scratches without an actual professional scratching tool.
Jerry and other "testers" merely spend a few minutes with the devices, and they don't need to save up to buy them. This means they simply don't spend enough time with the devices to get an every day experience (even if they give their videos catchy titles like "After 2 months with the phone"), and they don't check on these phones after a few days or weeks of 5-15 hours of daily use, since they never use them in the first place.
In that particular video Jerry unboxed, and went through his regular tests, one by one. However, he mainly focused on the back side of the iPhone. He didn't carry it around for days (in his soft cloth trousers pocket). Didn't got dust or fingerprints on it, didn't clean the screen repeatedly, never rubbed it against his T-Shirt, etc. In other words: these videos are fun to watch, but can not be called real scenario usage tests.
I doubt that famous Youtuber and Apple-fan "iPhoneDo" does carry it around either, since he claims to be a perfectionist. Or maybe he put on a full size screen protector (also covering the easy to scratch notch area) first thing after unboxing.
I'm not trying to proof anything here. Just mentioning this as the reason why I did not buy the iPhone 11 Pro when going to the store, after I have seen the scratches, and asking for your experiences/opinions. I was really looking forward to purchasing the new iPhone. I did a lot of reading up and waited for the day, but then was quite taken back, inside the actual store on my day of planed purchasing, by the scratches on every iPhone 11 Pro on display.
I might be ok with spending € 600 on such a phone, and have a € 35 screen protector applied, but not so much for a € 1319 (iPhone 11 Pro 256 GB) + € 239 Apple Care + € 45 case + € 35 screen protector = € 1638 = $ 1800. I will stay with my iPhone 6S for a while longer, meanwhile continuing to enjoy my headphone jack and 3D-Touch.
