Last word on the subject from me, because it is both tedious and trivial. There is no question that a change of vehicle colour needs to be notified. What is less certain is whether a temporary wrap institutes a change of colour IN LAW. Not in your opinion or mine, but in law. We know that it is the DVLA "view" that is does need to be notified, but that is a comparatively recent statement (a few years old: previously they did not treat it so.) But that has not been tested in law, as far as I am aware, and as I said earlier I do not know whether the DVLA's view has the weight of law.

Let us take an extreme case: you wrap a vehicle for two hours, then remove it. Does that have to be notified? I would say no. Then suppose it is left on for two years? Yes, I would say. So there is scope for treating short term coatings differently from long term..
