Opening images saved in the ProPhoto RGB color format from Photoshop displays in a different colorspace within Topaz. I see this color conversion frequently in my print work.
Edit / Preferences / General / Enable sRGB preview fallback
This mostly fixed the problem, however - while colors are mostly more accurate, they’re also slightly more saturated. I can deal with it, but it does stink.

A screenshot or description of the settings panel so I can see what adjustments were turned on.
