700p? Are you sure? I don't belive cinemas had about the same resolution as PAL at 576p. 720p is blurry too on big screens.

See the PDF kindly linked by the sibling (https://news.ycombinator.com/item?id=43919991):
• “The highest resolution that the expert assessors could discern in the highest performing movie theater was about 875 L/PH.
• “The horizontal resolution averaged over the six multi-burst groups measured on the screens of the six selected movie theaters was about 715 L/PH.”
L/PH = lines per picture height, i.e. vertical resolution
This was for 35 mm film.
Also, well-mastered DVDs with anamorphic widescreen can look astonishingly good on an output device that doesn’t interpolate its lines.
