Not really. Yes, there are some big ones that are non-canon, some of the most classic stories told in this medium, but many of the non-canon ones are, for lack of a better term, the "basic" DC stories. The ones that people read when first getting into comics and when they aren't as invested yet. They're also still actually in the minority of what one would call great DC stories. For every DKR and Kingdom Come and All Star Superman and New Frontier, there's Long Halloween, the Judas Contract, Sinestro Corps War, Year One, Tower of Babel, Return of Barry Allen, Killing Joke, etc. And yes, a lot of those stories needed to be in continuity to even make sense
