One of the few, if not the only, things MS has always been consistent with, AFAICR, are the so called "cumulative updates", which, nowadays, apply almost only to browser updates, but once applied to othe components, too. Now, KB4019276 is not cumulative, but both KB4316682 and KB4230450 are so. Hence, KB4230450 ought to supersede both KB4316682 and KB4109276, because it must include updated versions of the files and registry entries from both KB4019276 and KB4316682. Of course, there's then Murphy's law, and this one might be the feather that breaks the camel's back, so to say... one never knows unless we check (and then Schröndiger even goes on to say that even after checking we cannot really know what was there before...) so, just to remain on the safe side I'll state YMMV.
