You're missing out on resolution (4K) and picture quality (HDR, contrast ratios, color gamut) improvements by doing this.
Not everyone suffers from FOMO.
I've only seen one movie that was worth the bother and expense of seeing it in 4K (Rear Window).
The rest of the things you mention are mostly for a very small slice of theoretical people with perfect vision in perfectly lit rooms at the perfect height and viewing angle.
Beyond icons on a sticker checklist, they mean nothing to the 99% of people who just want to watch sportsball or eat popcorn while watching Disney films with their kids.
You can put lipstick on a pig, but most people are still watching pigs.
The OP is not asking for a TV to watch TV on, he's asking for a TV to use as a second monitor for his laptop. When it comes to computer interfaces, the difference between 4K and HD is enormous. Especially for text.
The footage is analog (on film). It was shot with 0 pixels, so 4k pixels on an edge doesn't matter. Side note, footage itself is a term derived from film (how many feet of film).
You can scan film into whatever digital resolution you want. You could do an 8k scan if you felt like it. You might run into issues where the resolving power of the film is less than the scan, but 4k is not an unreasonable resolution to pull out of well lit studio shot movie stock.
Plus it’s a black & white movie, and b&w film has a higher “resolution” than color too right? Because you’re dealing with silver particles instead of physically larger color grains.
Or something like that. Someone more in the know please check my math.
