Sorry for the delay! As promised, here’s some screencaps and I’ll share the rest of the equivalents that are shown here: http://www.blu-ray.com/movies/Predator-Blu-ray/316/#Screenshots
This is definitely (and thankfully) from a different master than the one that was used on the UHE. To my eyes, it looks quite close to the MPEG-2 version but has considerably more grain and slightly more detail - although that could be down to how the MPEG-2 screencap was obtained.
Opinions?
