But then Etulipa is showing their displays for billboard use with a >10m viewing distance.

And colour, other than subtractive panels like ACeP, needs either 0.042 mm for 2 x 2 colour or 0.028 x 0.085 for 3 x1 colour (stripe filters) for 300 ppi
Even pretty ancient SD TV was about 0.43mm, about 36x pixels in same space (inc R G B sub pixels) as Etulipa
Posters, shop displays and billboards, and only if cheap.
