We have seen a bug with the UltraStudio 4k mini, that would cause color shifting in the Kino Flo Mimik.
We were able to fix it by cycling from "Keep default color gamut", to "Convert to Rec. 2020" and then back to what it should be; "Keep default color gamut".
The settings are in the screenshots below, here are the main ones to keep in mind.

Default Video Standard: 1080 24p (or whatever you need)
