At some point the world's gonna figure this out and start making tetrachrome cameras and screens and it's gonna be the next big TV upgrade after 8k.

  Current technology is far more advanced than that, with hyperspectral cameras which can make images to identify different geological materials etc.

  15 years ago, Sharp released “Quattron” TVs with yellow subpixels. It was effectively indistinguishable, even in person.

    But was it distinguishable by tetrachromat?

      IIRC the yellow subpixels did not add any new colors, only increased the yellow beightness.
