I did a quick google search, it seems like iPhone 14 Pro is also affected? So based on what you said, the screen issue automatically covered by Apple Warranty?

The fix you show in the post is actually require right tools , environment (clean room), and knowledge to fix, common people will have problem to do it.
Also, I doubt that our local non-AASP phone repair service will offer this simple yet cheap solution in the video, most likely they rather go for replace screen option and charge more.
