Color management - differences between Nuke and DJV reading Prores 422 Proxy

[gdavid]

Hi,

I was looking for a free and easy player to offer our customers to review our shots.
DJV was top of the list but, as you can see from the screenshot, there are slight color differences that bother me.

As you support Nuke's OCIO configuration, I can't see any reason for this, and thought it was worth mentioning.

The movie I read was exported from Premiere, with these properties :
