See how right below the rind, all around the outer edge, there is this band? It's a different color than the rest of the cheese paste. It also looks to be a slightly more liquid than the rest of the cheese. That's one of the biggest indicators... that's what a brie or cam look like after a few weeks, and also what a lactic cheese with a white mold looks like. A normal blue with only blue will not have that (compare to your blues, for example, from what I recall in those pics, they were blue only).
The white mold on top of the blue in the inside, along with the more liquid paste confirms that there's some white mold, because blue mold, as aggressive as it is, does not have proteases/peptidases that are that active.
