Exporting Raw material in progress 444 is changing colors slightly

[SamehBijo]

I am having an issue when I render XMF raw footage that is coming from Canon EOS C300 M3,

the exported video is not identiacl to the raw footage ,its a bit pinkesh and the color correction team has noticed the difference .

Knowing that I am exporting in 32bpc mode and the color managment profile is Rec.709 Gamma 2.4

and I am exporting in Proress 4444 trillions of colors 

I tired turning off color managment without but still the issue is happening 

I tried rendering in different formats , but the same results 

Itried eporting from a different system , the same result , a slightly pinkesh footage .

How can I export exactly the same video in the same colors
