Short description of error
When using a different OCIO config file with a different colorspace than then Blender default the color wheels look kinda wrong.
Exact steps for others to reproduce the error
Download @Troy Sobotka (sobotka)'s OCIO config for ARRI colorspace and replace the contents of Blender's colormanagement folder with it: https://github.com/sobotka/ocio-blender-default/tree/arri-reference
Set the View Transform to Filmic.
Loading EXR files encoded in ARRI Wide Gamut works fine and they are being displayed correctly, however the colorwheels look off.
I am not quite sure what's going on exactly, but I think @Troy Sobotka (sobotka) will have a better idea.
