This is whack-a-mole. If I can design deepfake software, it isn't much harder to design it to specifically anticipate the user filming the result. The user would input their monitor specs, their camera specs, etc., and the software would produce a weirdly distorted video which looks perfect when filmed with that camera from that monitor.

Or, people just outright sell doctored cameras where you can intercept the input feed.

This isn't like adult content filtering, where all that matters is that kids can't get around it. You have to assume people who know what they're doing are going to attack your technical solution, and apply ingenuity in doing so. When the enemy consists of hackers, you can't ward them off with a hack!
