Composure output via DeckLink, colors doesn't match

Hi all,
i’m sendin a composure with a green screen and a CG_Layer out of a BlackMagic DeckLink card but the colors of my output doesn’t match with the colors of my scene, if i try to output the same comp in Viewport everything seems good.

Is it some option or configuration that i’m missing for the output? Even if i change the “Color Conversion” parameter of the OutputPass to “None” nothing change.

Is anyone facing the same issue?

Thank you
Luca
