Are Blu-ray remasters future proof?

[RiseDarthVader]

35mm is scanned at 4K which is close enough to it's actual resolution. Because when the 35mm records scenes with poor lighting or at night it only records about 2 megapixels of information. Which is the equivelent on Blu-rays max resolution. So when you are watching a dark scene on Blu-ray you are pretty much seeing an exact replication of what the uncompressed image would look like. But basically beyond 4K or 35mm you don't really see anymore details the only difference you would probably see is the grain structure.
