LCDs have actually used temporal dithering for ages to fake higher bit depth-- it let TN panels with 6 bits if precision per channel appear to have 8 bits of precision, and now it's being used for HDR-10 too!
Temporal dithering is much simpler algorithmically since you don't have to diffuse error over an area, just flicker a specific pixel between similar shades at the refresh rate.

Yep and you can really tell on certain shades of grey when the screen is mysteriously flickering. Thanks Dell.
