Could you please explain for those not in the know?

I realise that why I see is just one "interpretation" of the reality, but it seems sensible that one possible ideal for cameras would be to perfectly match my perception of the world. Is it just impossible because the difference in perception is just so big between individuals that what would be perfect for me would be way off for someone else?

You can also create (at least theoretically, no idea how they compare currently) cameras that are better than human eyes at things like resolution, contrasts and so on, and that seems like another possible ideal; but which one is more relevant seems very context dependant.

The challenge here is that your perception of the world itself performs contextual color correction. If you've ever seen those optical illusions where you see two different colors but they're actually the same (https://www.syfy.com/syfywire/another-brain-frying-optical-i... is my favorite recent example), that's a demonstration of the effect. So a camera that's trying to match your perception of the world can't just identify the "true" color; it has to identify what color it should print on your screen to generate the same perception as if the contents of the picture were outside your window.

I wouldn't necessarily say it's a bad ideal, though. Smartphone cameras do a very good job at automatically performing all the right corrections in most circumstances. It's just nontrivial, and thus unsurprising that the normal algorithms fail in weird edge cases like "the entire sky is deep red".
