Hey,
first of all: I'm really intrigued by this idea! Sounds too good to be true But I got a question. Inside of Resolve there's the color space transformer. If you'd put the transformer on the first node to turn vlog to arri clog und then on another node another transfer clog to rec709 (turning on luminance and color mapping), does it behave similar to your lut? Just curious.
