Can coverboard number be found without original display?

Hello
I've bought a used iPhone 11 pro which has an unoriginal cracked screen. I have bought a new screen. On other iPhones I can recover the TrueTone function without the original display. I use 3UTools to get the coverboard number and program it to the new display. But for some reason 3UTools can't read the coverboard number for iPhone 11 Pro. Is there a way to get the coverboard number without the original display? Or another way to restore the TrueTone function?
