A really big screen makes a huge difference. If you truly want to appreciate 4K content (be aware that most streaming 4K content is not good at all, surprisingly YouTube’s rentals have the best 4K fidelity of any streaming option I’ve seen) you need like a 70 inch screen at less than 10 feet away. I can assure you that with right content this can transport you into the movie in ways only a theater can match.

A great example I use is that in the Dark Knight, the thread the joker ties to the smoke grenade while getting into the school bus unwinds from his coat and is also purple. Like isn’t that insane to notice?
