Actually I’ve seen stills of frames from a real authentic 35mm print and the Final Cut 4K matches it very well. The neutral grade isn’t accurate at all.
Looking at a still frame, and seeing 35mm or 70mm film projected in a cinema aren’t the same thing. If you track down a copy of Blade Runner sourced from a 35mm film print, you’ll quickly see that the colours are nothing like what is on the Final Cut Blu-ray.
The Final Cut has a teal tint throughout the film, whereas the original 35mm release doesn’t have that tint at all.
