It is doable and you can get presets designed to mimic the look of legendary photography film stock like Velvia. But what they did back then was very much an analog process and thus also inherently unstable. Small details start to matter in terms of exposure times, projectors used etc. There’s so many frames and it took so much time, that it’s almost guaranteed there’d be noticeable differences due to process fluctuations.
