I think that as long as you keep away from lochsides in certain areas you'll be fine. Usually I'd say you'll likely not be bothered by any enforcement, but with restrictions lifting they may be out checking. They've had to go and paint double yellows in some places to stop idiots parking up all the roads because the car park is full. The area around the Dukes Pass, Loch Achry/Loch Venechar is pretty heavy with restrictions that go further away from the shore too.
Where are you planning to wild camp? It's banned in some places on the route you've got there, mainly around the Trossachs but possibly elsewhere.
