If anything, I think this screen should have the option of collecting ambient light from an even larger area.
It's actually somewhat genius. It's also interesting with color temperature. I guess it's a CRI of 100 in day light?
My phone has a setting for that.
And it's possible to do with a webcam + monitor: https://askubuntu.com/questions/23593/use-webcam-to-sense-li...
There's probably some software for that.
I think I saw a TV a while back that did, but that's 1 out of the 10 billion models out there.
I would never buy a TV with that.
CRI tests illumination sources, not displays. I suppose you could crank the display to max white and hold it up to the test pigments; that'd tell you something about the display's filters, but I'm not sure how useful it would be.
