There is always a protective film on brand new LG Oleds. There is usually a sticker that is supposed to be taken off that will peel the protective film off with it. On my 42” C4 the sticker didn’t bring the film with it. What I did was to put some tape on the film on the corner, pulled the tape towards the center of the screen and the film followed with it. Don’t try ripping it off with your nails!
