I don’t know if the test was properly controlled in terms of the strumming attack strength/speed, distance/angle from the microphone, etc.
To me, the best way to judge is to play one of V-class braced guitars. I clearly hear the difference between conventional X braced and V-class braced guitars. Also the best way to test is not playing a chord but play a single note especially at high position. That’s where V-class braced guitars shine.
If not playing high position much, the difference is not so obvious.
