Hello Erik, Chris, Sean.
I am having the same problem.
I am working with footage shot in Rec.709. I am making a dynamic link from Premiere to AfterEffects.
In Premiere: Sequence / Sequence Settings / Working Color Space: Rec.709
In After Effects: Project settings / Color / Working Space: Rec.709 Gamma 2.4
The footage changes color slightly; loses a bit of contrast and gets slightly warmer.
Did any of you find a fix to this issue?
Thank you so much
Best ,
Martin
