I’d like to add an ‘Action’ controlled script that changes the background colour on a ’Spinner’ widget, if the value is changed from the value calculated by a calc field in our software IOC.

That functionality should be straight forward to implement using a Display Builder Rule. The _expression_ can compare the widget’s PV value to the value of the expected value PV and change the background_color property of the widget if they do not match. Using the built-in rules is generally a more portable solution than using a script.
