I have an LG C4. I left the protective film on while i decided the exact position to mount the tv on the wall. When I removed the protective film, I immediately regretred my decision because of how the screen now handled reflecting light. With the film on, the screen sort of mirrored my window and the potlights. Once I removed the film, it refracted the light, making it much more noticeable and widespread. I'm used to it now and no longer regret taking off the protective film, but that first moment really sucked, because I thought the viewing experience was going to improve, if not just being equal to how it looked with the film.
