Is its support in DT that bad? From what I saw here [Questions] How to choose a DCP profile (if at all) - #41 by priort, apart from the warning you mentioned, it’s OK-ish. Perhaps there’s a setting to silence this warning? I currently use RT 5.10 for mine and apart from the fact that I’ll need to upgrade to get this fix instead of stealing white balance values from ART, it’s already good enough for my (arguably basic) usage.
