How is this relevant to the topic here? Dynamic range in audio matters only if you actually have some. It's absolutely possible to have 16/24 or more bits of dynamic range available but have the music be pushed so hot as to not use more than a few actual bits. The test you linked is just an example of such music. Regardless, it's easily discernible, as the loudness is not matched between the test samples. I don't even need to listen more than 0.5s to get to 99.95% confidence.
