Dr Watson’s principles of “selection and discretion”

Consider the following exchange from “A Case of Identity” (below). What do Dr Watson’s principles of “selection and discretion” do to the stories? Discuss this question in relation to TWO works that we have studied.
“The cases which come to light in the papers are, as a rule, bald enough, and vulgar enough. We have in our police reports realism pushed to its extreme limits, and yet the result is, it must be confessed, neither fascinating nor artistic.”
“A certain selection and discretion must be used in producing a realistic effect,” remarked Holmes. “This is wanting in the police report, where more stress is laid, perhaps, upon the platitudes of the magistrate than upon the details, which to an observer contain the vital essence of the whole matter. Depend upon it, there is nothing so unnatural as the commonplace.”
