I think the entanglement with light has to be present first and the others depend on it in order for the qualia to be there.
What if you’re a brain in a vat, and you’ve grown up plugged into a high-resolution World of Warcraft? If qualia are wholly inside the skull, their qualitative character can’t depend on facts outside the skull.
Well you need some input to the brain, even if it’s in a vat. Something has to either stimulate the retina or stimulate the relevant neurons further down the line. At least during some learning phase.
Or I guess you could assemble a brain-in-a-vat with memories built-in (e.g. the memory of seeing red). Thus the brain will have the architecture (and therefore the ability) to imagine red.
