my first question here is rather technical. Because of my interest in color management and ACES I am writing articles on my website about this topic. For 3D related tests I am using Blender.
So I am working in Blender with the OCIO environment variable set.
I checked the following what is best seen on screenshots and would like to know what I do wrong or there is a bug.
I marked the important areas on the screenshots from the Blender Compositor (which seems to work fine) and the Shading/ImageViewer which seems to ignore a part of the colorspace transform or clamp values as long as the texture is not a EXR file.
