I am surprised that on opting out of ad tracking in Android, they found that the opt-out flag was set to true, but the size of the tracking payload shot up i.e. more attributes being tracked. Not sure what to make of it? Is it possible its a legal thing that once you opt-out of ads, it enables less risk for the company and therefore more tracking, perhaps?

That would need to be reproduced. I suppose the app itself could also have been put in a different state / with different settings between the two events.

You are not being tracked. That is, previous data is not correlated with current data.

To get around that you just send everything every time.
