If I close one eye for a few minutes and then switch which eye is closed I see a very (very) subtle difference in hue.

Left eye sees a green tint; right eye sees a pink tint. It's more obvious when I'm looking at a white wall on a bright day.

I don't get this effect if I don't let one of my eyes adapt to the dark first.

Probably sense I was a child as I unintentionally did it for as long as I can remember (bc autism I guess)and only real difference is a very slight difference in prescription in glasses for each eye but genetics make my eyes bad so honestly don't know. The contrast difference is only noticeable at low light levels as one sees better in the dark which is weird.
