Gamma shift while using Media Encoder

Hello,

I was editing videos and rendering in AE , but my video  was about 10 go .So i decided to use Adobe Media Encoder to render , but i got a big problem.

The gamma between preview and real video was really different (See screen)

First screen is my 10 go video rendered in AE, and it looks like the same on the preview.
Second screen is my 36 mo video in AME with this settings : H.264 1920 x 1080
I changed the format / preconfig , and nothing change , allways this different gamma.

I jus try to encode my 10go video with "Handbrake" but i got the same problem , different gamma. Maybe the problem come from After effect , i don't know.

I'm using Windows 10 with AE CC 2017

Hope someone can help me !  Any insight on this will be greatly appreciated.
