Display Unknown Part - How to know if your iPhone screen is original or fake

And what if i dont have True tone, but also my phone doesn't show a message in settings for changed display?

Your display can be original and you can't have true tone and will have an important display message

does it matter or no

Thank you

I don't have "Parts and Service History" in my iPhone 14 Pro Max's settings > general

Idk why but truetone hurt my eyes maybe my eyes irritated everytime the screen change colors thats why I turn it off.

I noticed my brothers iPhone 7 is so much brighter than my XR

Brother am using iPhone XR no have true tone and not showing Unknown parts.
On more question please if screen replaced with original screen true tone option will be show automatically?

You answered a question I've had for awhile now. Only genuine iPhone screens are installed at authorized Apple repair shops. Never knew where or if I could buy genuine iPhone screens. Now I know. I can't buy anywhere.

I get my display changed with the original one ony
But true tone option is still not there
What should i do?

Pls what happened if my iPhone camera portrait is lagging and hang ,, but once I use normal camera is gonna be working perfect but once I change it to portraits is gonna be lagging

Will i worry to this? I dont have true tone and i have unknown part
