Well, either they have too much on their plates ... or well you know, the Japanese thingy with not being intrusive compare to we foreigners.
Or maybe, it is just not efficient to draw another panel to detail out the POV of non-essentials when characters are already conscious about it.
Doubt people would do same in reality, but with a few exception like people who take snapshot of every weird things they encounters ~ but yea~ why bother is beyond me, like my comment here.
