Could you explain more?
Do you mean the original cinema source or the home transfer?
One of my original issues with the cinema release was the relatively poor image quality, mainly down to the primary choice of the cheap and portable Sony FX-3 camera. The low light scenes were barely visible at the cinema. Basically, the first 25 minutes, I struggled to see any details in the blacks.
Wondered if it'd look bad on the 4k transfer.
