Hello Elle, I put together the ACES 1.0 OCIO config for The Academy. Hopefully I can help answer some of your questions. Specifically, you asked Does anyone use ACES in conjunction with ICC profile color management? If so, do they use OpenEXR to store RGB data? We have found that many people

Afaik, ocio supports color transforms, not color management, complementing icc. Ct~ changing the look within a given color space, or along a path of preconfigured color spaces. Cm~ preserving the look automatically between arbitrary color spaces having known arbitrary color characteristics.

The specific question was whether photographic image editors should allow writing nonlinearly encoded RGB data to OpenEXR files, or whether instead the RGB data should be converted to a linear gamma ICC profile before being exported as OpenEXR. In the usual photographic workflow, editing
