Hi Gonzalo,

the main problem with sRGB (and Rec709) in ACES is that nuke-default is adding the sRGB-Transfer Function to the linear material,
whereas ACES is also applying a Render Transform (RRT+ODT) which deals with the HDR content, and in order to make space for the content above 1.0
a value of 1.0 is compressed to 0.8 which makes the export appear darker.

A more profound discussion is here:

Hi, Eberhard.

Yes, that's more likely what I am seeing.  Thanks for the detailed explanation.

Cheers,
