3rd party display - genuine display message

Hey there,

my iPhone 11 screen is broken and I‘m thinking of repairing it by my own. So I collected all needed informations. At least I read about the genuine display message, which is popping up. I can‘t fix this by my own (already watched the video and I‘m to afraid of a chip grinding removal). So I called a repair service nearby and asked for „only doing this chip thing“. He told me since iOS 14.2 the Message won’t appear anymore. Is this True?

Actually the message itself isn’t this bad. I‘m planning to use a refurbished display, so quality will be fine. But I‘m thinking about selling it on future and surely a buyer will not be amused about this stupid fake warning.

So, did anyone managed to replace the display without getting a hint about genuine display and also without switching chip? Or is it still the same problem?
