Intel MacBook Air and MacBook Pro LCDs do not have security features and are NOT paired to the Logicboard. True Tone will work (both third-party and original.
Only M1 and above models are paired. True Tone will be disabled but auto brightness and FaceTime Camera works.
They are serialised, but only for the purpose of verifying your warranty to ensure your Mac comes with the same LCD it is sold with, and even then not all Apple stores check them.
The hinges for the Macbook Pro 13” 2016-2017 (A1708/A1706) are physically different from 2018-2019 (A1989/A2159). This only applies to original Apple parts though.
Aftermarket third party OEM LCD assemblies may reuse the same shell but put in a different LCD inside.
In any case, if you use a 2016-2017 on a 2018-2019 Macbook Pro, not only will True Tone not work, the entire LCD will be extremely dim after it logins to the desktop to the point it is nearly not visible.
So if the display works, but there’s no True Tone, it means your OEM or Third Party part or the original part has a failed True Tone camera. It is rare, but possible for original parts not to have Facetime camera or the True Tone sensor working.
T2 does not affect anything. True Tone will be disabled only on M1 and above Macbook Pro and Macbook Air. The LCD has to be paired, which currently only Apple and AASPs can do. Facetime camera will work.
If True Tone or the FaceTime camera does not work, it is either the LCD itself, or that you have shorted out a component on the Logicboard.
Very slight misalignment when fixing back the LCD connector, or that your battery screw was not removed well before the lcd is replaced can short out the camera or True Tone component circuit on the Logicboard.
You have to tell the Chinese sellers you want True Tone, camera and auto brightness to work, and get them to show you the testing videos.
