I've just seen a lot of crappy cellphone bootlegs, and crappy Infinity War bootlegs specifically. Big movie comes out, everyone's scrambling to get their cracks in, you end up with a lot of memes made out of pictures of theater screens. See enough and you start to pick up on the patterns, then the HD stuff starts coming out and you really notice the difference. Cropping's off, color grading and exposure are wrong, picture's a little smudgy 'cause the guy can't hold the phone still... Compare it to the actual scene, it's a little tilted and it's got that sorta washed-out bright blue cast you get when you try to take a picture of another screen.
