@Lala2 4K is a digital resolution, so while films shot in digital formats wouldn't have existed prior to 2009, films shot on actual film stock have effectively been subjected to compressed lower resolution scans when digitizing the image from the actual film reel that has the capacity to lose a lot of finer detail that can be restored by rescanning the film at a higher 4k resolution. Effectively, any audience who would've seen these films in their original theatrical run would have watched a higher quality version then is available on any digital format, as the image detail is really only limited by the size of the film stock (typically 35mm) as opposed to limitations imposed by digital resolution which segment the image to fit the amount of available pixels. Because 4K is one of the highest resolutions the eye can perceive, it's most effective at recapturing the experience of the film as it would have been originally presented.
