I removed it for my 55 B6 as it was mentioned in the user guide. Check your user guide though..I got my oled last week. Now i got the front film removed from the LG technician but he didn’t remove the film on the back and said heat dissipation happens from front, its not to be removed although if you insist , I can remove it. So I haven’t removed it yet.
Have you people removed the film from the back of the panel?
