I’m a bit confused your display died so why are you thinking replacing the main logic board would help.
Second the chips are within the T-CON board and this is not available as a spare, and besides the setting is held within it and the key needs to match what the main logic board is expecting in the newer M Series.
Sadly, Apples greed of wanting the whole enchilada is slowly killing both the recovered parts (reuse) space and slowly chipping away the independent repair industry! Both personal and pros with the skills.
So you need to get the part from Apple as you need access to their Calibration Tool which is behind a wall and set to the displays ID so you can’t cheat!

@tsmithnz - The way you started your question lead me to think you had a newer M series system not the older Intel model.

=== Intel Series ===
***So as long as you have the older Intel system and you are using a used display on your system you will have a working system!*** The TrueTone setting is held within the T-CON logic. So you just can’t use a virgin display without access to Apples calibration tool.

=== M Series ===
***''If on the other hand you are working with the newer M Series system… All your options require the deeper skills in some form.''***
***Option 1:*** While transplanting your good display onto the system with a damaged display will get you partway you have no means to calibrate the screen so you will see the artifacts of mis aligned backlight. Are you willing to live with that?
The other option is getting the other system and then go after the needed display Assembly from Apple which then gets you access to the calibration tool. But this does not fix the original system.
***Option 2:*** Is really no different than Option 1 as the original issue of calibration has not been solved.
***Option 3:*** While it does look like a loss, you might find the replacement systems case is banged up so you can leverage some of its parts if they are in better shape than the others.
***Last points on Option 1:*** The T-CON board is hard wired to the displays LCD panel internally.This requires even more work to desolder than trying to swap out the chips. Both are Brain surgery!
As far as the display’s Hall sensor that is on a separate assembly so damaging it won’t likely lead to a calibration. I think that’s a sizable gamble.
