> Saturation can't be controlled on a per-pixel basis because, per the article, they're tuned to a specific wavelength at any given time.

Where does the article say this? I couldn't find it.

Honestly might just be the limits of photography, there's so much contrast between the ~97 L* brightness of pure yellow and black that the sensor might not be able to capture the "actual" range.

I've been called a color scientist in marketing, but sadly never grokked the wavelength view of color. It sounds off to me, that's a *huge* limitation to not mention. But then again, if they had something a year ago, its unlikely ex. Apple folds its microLED division they've been investing in for a decade. Either A) it sucks or B) it doesn't scale in manufacturing or C) no ones noticed yet. (A) seems likely given their central claim is (B) is, at the least, much improved.
