How to preserve saturation among luminance in AE (as Premiere do when convert HLG to Rec709)

Hello,

I try different effects, bu i can't found in AE how replicate the Premiere Pro conversion.
The pb is that we haven't the same option to preserve saturation among luminance and others little setting ...
The screencapture (sorry it's in french) shows my setting in the Premiere Pro color management panel and i want to do the same directly in AE.

Is it possible to replicate this setting ?
When we interprate footge in AE, we haven't got any options ...

Thank you
