Apologies, I think I jumped the gun.
Can you tell me what format you’re export from ae/me ?
Exr is an image file, so you export exr sequences, they have the ability to hold lots of data.
Colour management is how aftereffects reads in the colour data of the input file, put extremely simply.
ACES is a version of colour management , it is very good at it, but can be complex
I mentioned these as I’ve had issues with getting log back out from after effects unchanged too.
But the best place to start is how are you exporting them, to what file type?
