When do you peel off protective film?

I just received an Amazon Fire TV Stick and most all of the components, remote, AC/USB Power Supply and the Fire Stick HDMI module had a protective film on them. The packaging was a thing of beauty. When do you, if ever, peel off the protective film over displays, etc? I do immediately and it bugs me, maybe more than it should, when people leave it on as protection. Whatever you’re protecting looks a lot better without the film.
