If I use AliExpress LCD, will there be a limit to the function?

Well... It's not that simple! The source of the part is the key!

A new from the factory assembly (virgin) won't have had its camera calibrated for the TrueTone services so the camera and the brightness services won't work.

If you got a used display from what was a working system the calibration had been performed and is stored in the displays T-CON logic ROM and will work correctly with your system.

This issue is only a problem with the 2018 and newer MacBook Pro's that have TrueTone.
