Short description of error
Cycles ignores Texture Tab Color Space setting (IDT) and burns the Display ODT into the image (tested on EXR format output)
Cycles should import the pre-transformed Texture from its [[ URL = https://developer.blender.org/T63571 | Color Space IDT ]] to Scene Working Space (scene referred space declared in OCIO configuration) and apply the Display ODT only in the Render Framebuffer (Display ODT option is also lacking in the Render Framebuffer).
Currently if you feed pre-transformed maps (at least for EXR format textures) it works as expected. Below a descriptive graph of the current chaotic behavior between 3D viewer and Cycles.
