Mplay and Renderview in Houdini are displaying linear .exr files with the OCIO ACES Rec 709 view transform differently than Nuke and the Redshift Renderview display them.
For example I am rendering a frame in Redshift and viewing it with the Rec 709 ACES display transform and in Nuke and Redshift Renderview the images look identical, and there is lots of detail especially in the shadowed areas, however when I display the exact same .exr file (rendered by Redshift) in Mplay with the ACES Rec 709 view transform it looks different, especially in the darks; a lot of the detail is being lost in the blacks and shadow areas to the point where I can't use it for colour critical work.
I am using Arch Linux with the OCIO and OCIO_ACTIVE_VIEWS env variables set. I'm using ACES v1.1 config.
Is there any obvious reason why Mplay would display the linear .exr differently with the same view transform applied?
I really love using Mplay to preview renders but I have to be able to trust that what I'm looking at exactly matches what I will see in Nuke and other software using OCIO and ACES.
