If your question is, does the lid angle sensor need to be programmed by Apple, then yes.
When you replace the display, it is mandatory to replace the Lid Angle Sensor under Apple's repair guidelines. The Lid Angle Sensor can be replaced alone, but in either of these scenarios the system needs to be run through System Configuration.
Without this, you might experience some strange issues related to sleep/wake.

***UPDATE***: After having done some extra research on this, I am finding that it is less likely the sensor is paired and more likely the little chip on the cable which reads the magnets orientation needs to be programmed or calibrated.
As long as the sensor has been programmed it is likely to get you going again. So a used cable would be the way to go, but still may not be a guaranteed fix due to potential variances in the magnets in use as well as positioning.

***UPDATE 03/13/2024*** - For sake of completion I am putting this in here for anyone who stumbles into this post. There is now [link|https://notebooknerds.de/en/nerd-tool-1/|a third party tool available to calibrate these sensors|new_window=true]. It is quite pricey for one time use, but for anyone who does these repairs regularly, it is a worthy investment.

***For Bonus Points***: Because I did an awful lot of research on this, here's the full picture.[br]

Since the magnet is mounted on the display hinge. Apple replaces them in tandem to calibrate the Lid Angle Sensor to the new display's magnet rather than using the older calibration. That way the results are as Apple expects. [br]

Without the programming altogether (as would be the case for a new cable), this is the sort of behavior others have reported. The screen just doesn't go to sleep. Ever.
People in the repair community have circumvented Apple's programming by desoldering the chip from the original cable and soldering it to the replacement cable. This way all the original programming is retained. This isn't a "for everyone" method, since it requires some pretty specific skills, but it's a viable solution.

So, you may have luck using a sensor cable harvested from another Mac. Reports vary. But you'll definitely have the same issue you're having now if you replace the cable with one that's unprogrammed. Like many you might source online from various vendors.

I am still trying to dig into the exact what's and hows, but not having one of these kicking around makes this less feasible. Plus I am doing some guesswork as to what the actual IC is since the markings on it do not help me much.

It is paired both to the screen and to the system (logic board).

The Lid Angle Sensor can be replaced alone, but in either of these scenarios the system needs to be run through System Configuration, a process which ties all the parts together using the parts' serial numbers.
