Anecdotally, I've taste tested various types of coffee using different brewing techniques (regular pour over, Chemex, French press, and espresso), and I can definitely tell the difference. For some specific examples: espresso was by far the most acidic and concentrated (which makes sense if you know how it works); the French press brought out the most bitterness; Chemex produced the least bitter and most consistent coffee regardless of the types of beans (for me this was a downside as I could barely taste the difference between beans, and all of them tasted more bland); and pour over was a nice middle ground (my favorite). I admit that my test was not blind or scientific by any means, but I didn't know much about the brewing methods back then, so at least I wasn't swayed by any preconceived ideas of how they should taste. Also, it's entirely possible that most people would fail this test, but IME most people also don't particularly care how their coffee tastes. This is evidenced by the popularity of Starbucks, which trades flavor for consistency by over-roasting their coffee.
