Yes, I think that would most commonly be the case. But in the example of this video, the first thing I noticed and was surprised at, was an absence of any sign of room reflections in the mids and highs. Did you by any chance listen to the video? I believe it was a well-treated room. Usually, I hear all kinds of echo in these YouTube equipment demo recordings. Only because of that did I feel that the video allowed some window into the general sound of the speakers in the highs and mids.
All I can really hear in that video is the room the speakers are in, it's immediately apparent.
