This looks very promising. The sample is too pink, but the shots Dr Dre provided look great and I look forward to a version of this material with good color grading.
However, while there’s no question that working on this in 4k is great, I don’t think there’s much benefit to releasing it in 4K with that amount of DNR. It’s not particular bad DNR for 1080p. However, there’s not a ton of inherent detail in release prints; adding an extra step of information loss starts to kill any benefit that a 4K release might provide.
