It's easy to tell if it is factory or add-on. Look at the edge with the window partially cracked. If you see a clear 1/4" of window along the edge, it is an add-on. 95% is a violation for front windows in nearly every state. But, I think you can get away with it in many states if it is on the rear side and rear windows. I doubt any factory tint would be that dark for front side windows.
My '88 supra had add-on window tint that I had to scrape off. It was sun-baked and long lost it's optical clarity. But it was only about 75% or 80%
