PP23.4.0 BETA (build 15) MacOS 12.5
So AME, like PP, has a global 'auto detect log color space' toggle in General settings.
This is NOT LINKED to the PP 'auto detect log color space' setting and also appears to be locked in at the moment the sequence is 'sent to media encoder' - either by direct keyboard command or via the export tab. (i.e. if you change the AME AutoLog toggle after it is in the AME queue the interpretation in the sequence export will NOT be changed)
Thus it is VERY LIKELY that exports that are sent via media encoder will NOT MATCH the levels/colour in PP unless PP and AME have the same AutoLog settings.
I think these settings are per machine - so in shared environments would need to be set across all machines and also would need to be re-enabled if/when preferences are reset. I can see this getting very messy on bigger shared projects with multiple editors with multiple source colour spaces.
Maybe the AutoLog setting should be with the ToneMap choice and be per sequence, maybe with an individual clip override.
