Just to clarify, many third wave shops do serve medium and dark roasts. My point is that third wave coffee shops often call a roast dark when they are actually medium or light. Additionally, I think only light roasts really qualify as third wave.

Most of the coffees you listed look like actual dark roasts.

"Full City Roast" with "lemon zest" in the flavor notes raises some red flags for me. Indeed, from the reviews: "Yum! I don't like dark roasts, and this is not a dark roast which is why I liked it. Lots of chocolate. Very smooth, not bitterness, a hint of fruit as it cools. I really enjoyed drinking this."

"Imunika Black" might also be an exception: the "blackberry" tasting note makes me think it isn't very dark.

I see more with citrus or other fruity descriptions, and I doubt those are dark roasts either.
