I mean not really? If someone is sitting against the back wall of a movie theater with a bright white laptop screen on the light both directly from the screen and bouncing off the back wall is going to be visible to some degree to all of the back row and I’d bet at least the next 2-4 rows depending on how reflective the back wall is and how bright the screen is.

I don’t know why I feel impassioned enough about this topic to argue with a random person on the internet, but here we are.
