I think this is an important point. Also, there are a number of additional elements that make the film exceptional that the book lacks. My favorite example of this is the deliberate misquotation from America, A Prophecy: “Fiery the angels fell; deep thunder roll’d round their shores, burning with the fires of Orc.” Fell replaces “rose”, signifying that these off-world replicants are angels falling to earth. Truly more human than human. Additionally, for an example of extrapolation, Blade Runner does not explore the consequences of exponentially increasing reasoning/abstraction that an artificial intelligence could theoretically achieve which human intellect could not understand.
