I'm getting the same problem.
Using Portrait Pro 17 as a plugin from Photoshop CS6, and working with sRGB embedded files.
Colour shift is either more red, or over saturated. Only when viewing in Portrait Pro - the saved / exported image back to PS is fine... so this for me is just a viewing issue, but makes life difficult.
Mac,
OS 10.11.6 (E Capitan)
