There may be some of this, I believe the video used mostly room mic to give a better impression of what it sounded in the room.
With some of the comments being made, and different player tastes combined with variables in the video delivery system keep any video demos from being "gospel". I'm staring to wonder if it's worth the considerable effort and time taken to put these videos together that show the amp's depth of features and the relative differences between cabinets. There's a lot of information being presented aside from anybody's personal tone preference or playing style. Are you critics so good of a player that you can't put personal bias aside and take this for what it is?
I've never really understood why, when people go into a store, and try out a new bass, or someone demo's a new bass in a video ; they immediately start slapping the hell out of it.
If slap is so important / popular, where are all the modern records / bands featuring slap bass - where are all the hit singles?
Likewise, though to a lesser degree, with muted playing - it features to some extent in popular, modern music, but it's not the primary concern of any jobbing bassist.
None of those extremes tell anyone anything really vital to a bassist's bread & butter, and how the instrument will mostly be used.
I think product demo's are useful, interesting, and important tools, but they really need to let the instrument / pedal / amp / cab / plug-in sing, and show it in it's best light, whilst casting a wide net.
FWIW that's not my commentary on
your product demo's - as I have yet to watch them - it's just my stance on demo's in general.
