You are impossible and I’m reading you well don’t worry.
Let me summarise for you: If you read the OP, images were presented showing a behaviour and seeking for explanation as to why or the meaning of it:
What I did is showing that a basis change, a simple 3x3 matrix, causes that. Again, the ACES 1.x DRT does the same and it is RGB rendering. No need to go down the rabbit hole or 4-dimensional chess game to find an explanation.
Fiction? How so? We do exhibit images that have been rendered in a common working space on different displays with different technologies, e.g. monitors, TV, LED wall. This is how we produce all our movies. We do that on a daily basis and I’m pretty sure that Framestore, ILM, DNeg and hundreds of vendors do the same.
