I havent been to the movies in 2-3 years at least, so when i got to my local big screen with their Sony 4K pj something distracted me on the screen.
if you've looked at laser light point, on a paper, i'd see this wiggle-jiggle of the light "pixels", it wasnt a stable/flat light spot like you have with a regular flashlight(i havent seen led ones)
and its not the film grain.
i looked on the Sony website and thy dont seem to have lasers in their cinema pj...

My guess is that it was shine from metal particles used to give the screen a positive gain. A lot of theaters have it nowadays as it is also required to keep polarization for 3D. Did you notice if the screen was unevenly bright? Brighter in the center than the edges?

Possibly screen issues (sparkles, texture)?

I've noticed more theaters using curved high-gain screens, lately, to avoid hot spotting. Good point about 3D capable screen introducing additional sparkle.

This is why I've gravitated towards lower gain screens in my own theater - I hate sparklies / sheen / texture !! Takes me right out of the movie.
