Hmm, I ran into another issue, severe luma clamping before applying any processing. It simply hard clamped luma to 100 when applying Chromatic. Even changing their “illegal Colors” to “Do Not Clamp” had no relief.
With 24 hours after I reported it they acknowledged it. Said they believe it may be related to the specific GPU (Late 2013 Mac Pro with AMD FirePro 500 in my case). In about 3 days they had a build for me which fixed the issue.
Given what you’re seeing you should send them screenshots using the same source with CG and Chromatic with only the lut applied. Include Before and After scopes as well. I’d also include the GPU just in case that’s a factor.
