Any improvement to the D810 camera profiles, or are beta v2 profiles still needed? (posterization)
The release notes for LR 5.7 (note: 5.7, before 5.7.1) included:
"Improved quality of Camera Matching color profiles for the Nikon D810. Fixes visible banding issues with the Camera Standard, Camera Vivid, Camera Landscape, and Camera Monochrome profiles."
The original support for the D810, with the dodgy profiles, was in LR5.6.
To my understanding, the improvements incorporated in the beta profiles were consolidated in LR5.7. But I don't have a D810, so I can't confirm.
