Movs always coming through as gamma2.2 photo jpg

Hi,

I have a remote artist who uses SG Create to send DNxHD rec709 quicktimes to my ShotGrid. For some reason when I download them they always end up as photo jpg and gamma 2.2.
What, where, how??? Is thie SG Create doing funny stuff or SG itself? I never use SG Create but my own publish tools and have never seen this before.

Cheers,
frank
