> Brightness and saturation will probably be maxed out but with a cheap TV, it looks more like "normal" on a more expensive model.

That probably mimics Samsung TVs, which are popular for that reason but look like crap.

The actual best TVs, picture wise, are among the LG C series, which are surprisingly dim and unsaturated. That said, mine has held up terribly so I won't buy another. My $200 Onn looks good enough to my eyes and lasted longer.
