In awe of Alien 4K on Apple TV

Just wanted to stop by and say I decided to buy Alien on Apple TV and I’m legitimately struck at how insane the quality is. I understand they did a 4K remaster but besides the audio + 80s synths you could never tell this was shot 45+ years ago. There’s some scenes for me that look objectively better than anything Prometheus and Covenant have. I’ve seen a lot of 4K remasters and this one just makes me wonder what else is a game-changer in 4K from the past?
