How long does a 1080p movie take in good quality?

Question

Video

Essence of the question: I want to download a movie from a 1080p torrent. There are tons of versions of the same movie with different sizes. //I understand that more size means more quality.
But I want to ask those who understand: What size is better to download a movie in MKV 1080p format so that the quality is excellent and the file is not very large?
//at 32GB movies very quickly clog the hard drive.
Tell me, for example, will the difference between 1080p at 4GB / 8.5GB / 15GB be noticeable on plasma? Does it make sense to download 15GB if you can't tell by eye?
Z.Y. Plasma 100Hz.

Answer 1

I have a 65 inch 4K TV. I download according to the availability of time. If a viewing is scheduled for the evening, then I merge some of the largest. But lately I've been downloading mp4 1080p for Apple TV (usually from 7 to 25GB). Is there a noticeable difference? Minor, mostly in color and detail in effects. But I don’t notice them while watching, unless of course it’s some kind of avatar where a lot is focused on special effects.
If you have a disease to make a home library - it passes.

Answer 2

Buy a couple of screws for 3+TB and don't worry about such questions - compared to the price of plasma

Answer 3

it all depends on the source and compression parameters, on one film you can’t find the difference between 32 and 6 by eye, on the other the difference is very noticeable,
30+ GB for 2 hours is a “ringing” sharpness, not every camera produces this, but what shot on film and even more so.
