Shane Ross is totally correct about this.
I would think almost no one here has a calibrated BROADCAST monitor. If you did you’d understand network/cable delivery standards and what video should look like. Plus how things get screwed up down the chain (cable providers mistakes, home viewers setting up their sets too bright, etc.) My brother loves the brightness and saturation cranked way up. I just tolerate it since if I ‘fix’ it for him he’ll just change it back.
As for the squished 16×9 producer’s problem.
Years ago I used to receive standard def master videos from one of the most famous cable networks and the labels would often say 16×9 when it fact they were 4×3 letterbox. Other times they’d be 4×3 center cut (sides cut off). Our delivery standards always said 16×9 only. People screw up sometimes. My guess is the producer’s cable provider had some inexperienced operator who didn’t understand the settings of his encoder and sent it out wrong.
At trade shows like NAB you can see all kinds of Broadcast monitors from Sony, Panasonic and others. They aren’t cheap. They exist for a reason, to know your stuff looks right.
