Ok, I just removed the tinted film. Mine appeared to be glued to the camera side, but each time I pulled the bezel back it would unstick from the adhesive and snap back to the bezel side. As a previous person said, be careful because it's easy to scratch the back of black bezel, which is noticeable from the front. I put a very small small scratch in mine. Otherwise I can say that, as promised, the image quality looks much better. I'm worried that it could be too bright in outdoor light, but frankly I don't plan to use this outside. I can't test that now as it's just about bed time.
Interestingly, without the tinted film, you can now see the little plastic camera in there (at least that's what I think I'm looking at). The tinted film is actually a bit of a mirror which normally hides the camera behind it, so without it there you can see straight through to the camera which looks like a little 8-pointed star-shaped cheap piece of plastic. I wouldn't be surprised if the film is there purely to hide the little camera. I personally would rather have a working camera over a hidden camera

I used a kitchen knife after being unsuccessful with a utility knife. I'm sure someone can find an easier way. Getting underneath the film without damaging the bezel wasn't very easy. By the way, I did NOT find a way to pull back the bezel any further. I pried it open just enough to see in there and move around with the knife.
One more thing: before getting too serious with the knife, I did try inserting some tape to try to stick to it and pull it out with. Didn't work. It may be adhered on both sides. Not exactly sure. For me this was a one-way thing. The film is fairly damaged and I won't be able to re-insert it.
Good luck.

PS: Below is my sample without the film. It's part of my kitchen, at night with fairly dim indoor lighting. Before removing the film you wouldn't see much at all.
