Color shift in Media Encoder when sending jobs via script

We have a script running in After Effects that uses the RenderQueue.queueInAME() function to add compositions to the adobe media encoder.

It works but all the exported videos (doesn't matter which format) have a slight shift in contrast. They are all slightly brighter with less contrast.

What we found out:

In After effects the working color space is set to none and assume working gamma is set to 2.2 (SRGB). To reconstruct the output we get from the medie encoder we can set the working color space to SRGB IEC61966-2.1. So switching to this color space gives us the look we accidentally get out of the media encoder when sending stuff there via script.

This isdefinetly a bug that should be fixed. If you want to reproduce here are the steps:

- Set your project working space to none

- Send your job to media encoder via RenderQueue.queueInAME() function

- open the export settings and compare source with output. You can already see the color/contrast missmatch

Now do the same but don't use the script. Just use the command "Add to adobe media encoder queue"

Check your export and you will see it has no color shift. So there seems to be something broken with the script function or it just sends some hardcoded color profile we don't use.
