So, they see 10x the color data, they see it _without_ added tech, and why do I have a suspicion that they still get labeled as "inferior".

This page is a pretty decent explainer for human color vision... I'm afraid I don't have a link about birds. Maybe someone else will!

It’s much easier to see with Starlings but the light has to be right.

I have a bunch of shots like this one that shows the iridescent nature of the starlings fairly clearly. Obviously it would be much more dramatic if the camera could detect further into the IR and UV but this is unmodified out of a Nikon D5300 and is how I remember it looked to my eye.

I’ve never noticed this with crows or ravens around here but it’s common to see that flash of weird blue and green on magpies.

i think you already know, but if not:

there are human tetratchromats, they are rare

all women

because women get two copies of genes related to vision which are on the sex chromosomes: XX, while men get one copy: XY. so only women can get one normal gene, and one with a mutation that shifts one of the three cones, thus giving them tetrachromacy

normal people can see 1-10 million colors, such rare women can see 100 million or more

The exact filter layout varies depending on exact sensor types/brands (there's more than one type of filter), unless filter is removed, they all filter out infrared and ultraviolet. So you can't "see" ultra-violet by just editing RAW. Nor printers and screen can render it.

One might amplify visible colors and add fake colours, such as violet (instead of UV, which can't be seen by humans anyway)

Did you know that phones would be really shiny if you could see radio frequency?

You can't ever see what birds or any creature (or Alien) with better colour vision sees, but you can downgrade to what dogs or cattle see.
Some women are a bit tetrachromatic on retina but eye filters it.
