Different series have different issues, so it’s important to stay focused on what you have for a system. The display technology of the MacBook Pro’s was changed to a mini LED zoned backlight in 2018 which is often what people see and talk about when replacing the display as there is an additional step needed to calibrate the display so the LCD panel and the backlight are in sync.
The source of the display then becomes the issue as Apple didn’t allow the display makers access to the needed firmware to make the display fully work. This is related to both TrueTone and the FaceTime camera so a display that fell off the back of a truck on the way to Foxconn to be assembled with the rest of the system won’t have the needed firmware. Here a used display will allow the camera to to be workable but TrueTone won’t be active as again Apple requires a calibration step.
So then your question is how does one Calibrate the display, this requires getting the display from you guessed it Apple! As the tool is still currently held behind a paywall.
Hopefully that helps explain why you were getting different answers, So let’s now start talking about Your System!
You have two options getting the display from Apples self repair portal or getting a used display. Getting the part from Apple gets you access to the Calibration Tool, the used display will allow the camera to work but you loose TrueTone.
