I think that just about everything you'll see in a store is aimed at "Wow" factor.
Back when the stores stocked a lot of CRTs, they had special programming (generally nature scenes or music videos with helicopter shots of landscapes & so forth) piped in that avoided showing any straight lines, because unless the tv set had an Invar mask & good quality-control, lines would wave all over the place (especially toward the edges). I once succeeded in tuning in a station on some of those that had a prison movie with lots of cell blocks, and the grids were rarely rectilinear. That was back when brands like ProScans were plentiful: Pretty packaging but not much in the way of a well-focused image.
They seem to amp up the color in stores because they want to catch your eye. With all the different models & the various distractions there, "more is more" seems to be the rule. How many people actually have the chance to sit down at a store and watch a tv set for a long time in a setting similar to their homes? The quiet & comfortable setups are mostly reserved for those 5000-dollar jobs.
I have noticed that in most showrooms now, CRTs are tough to find at all, and of course those big plasmas & LCDs are impressive because of their sheer size, all right. . .but the resolution is often lousy.
