FLATSCREEN: Frankly, who watches a TV on standard factory setting??? Anybody knows the sets should be adjusted and calibrated by respective representatives to be fair.
I think you're giving the general public far too much credit. Aside from those of us that inhabit places like this I think most people do exactly that, plug the TV in, leave it on the factory settings and never even consider that it could look better. Indeed if they're anything like my brother-in-law will insist that properly set up the set looks worse and insist you put it back to the factory settings...
In Curries they have an LCD, Plasma, and Led all calibrated and all looked great,
I've never been in a Curries where ANY of the TVs were even running a decent source, they're always fed by coax and look dreadful, John Lewis is the only big store that I've ever seen running an HD source.
