Comment (by john-parton):
Here's some information that might be helpful:
[https://stackoverflow.com/questions/45888263/strict-comparison-of-
dictionaries-in-python]
It looks like there's two approaches:
1. Convert both the old value and new value to some string representation
and compare them. (Either using json.dumps or pprint.pformat)
2. Recursively compare the values
I think (1) with json.dumps would probably work best. pprint.pformat was
suggested to handle objects that can't be json-serialized, but obviously
everything that can go into a JSONField can be json-serialized.
