I might be the one and the same Michael… 😉
As far as the sequence goes, since the AAF roundtrip bakes in the conform and color, you may need to refresh the sequence once back into Media Composer. I have found this necessary with things like FrameFlex (although there are still workflows that it can trip up on). So with sequence in record monitor, go to clip/sequence/ refresh all. Let us know what happens!
