Oh, right, well LPP is a type of film stock, developed in the late 70s/early 80 that doesn’t fade when stored properly, so it has the original colors even now. But BD is sourced from the original negative, which has much more detail than a print you would have seen in a theater (this 35mm LPP print is one such) and the optical copying of the film also caused the contrast to increase, which meant more crushed blacks and blown-out whites than the original negative (or the inter-positive print, which was used for the GOUT master). But in short, those black levels are probably pretty accurate to what would be seen in a movie theater.
