Engadget ran a reminder piece on this and it is worth repeating here because it catches people every single year. New televisions frequently ship with store or demo mode already enabled, including sets bought online that never sat on a shelf under a single fluorescent tube. The mode cranks the backlight, pushes contrast to fight retail lighting, sometimes loops promotional overlays listing the resolution and refresh rate, and on a lot of sets it quietly resets any change you make every few minutes so the next shopper walking past sees the manufacturer's chosen look.
That last behaviour is the actual trap. Somebody unboxes a set, thinks the picture looks blown out and wrong, spends an hour walking through brightness and gamma and local dimming, gets it looking decent, turns the thing on the next evening and it is blown out again. Then they conclude the panel is faulty or the TV is broken and start a returns thread. It is neither. Nothing they changed was ever being saved.
So before touching a single picture control on a new set, go find the usage or mode setting first. On the TCL in the article it was under Settings, then Advanced Settings, then Usage Mode, switching from Store Mode to Home Mode. Other brands file it as Demo Mode or Retail Mode and bury it somewhere different. There is often also an Auto Store Mode toggle that will helpfully switch it back on for you, so kill that too.
While you are in there, whatever eco or energy saving mode the set defaults to is worth a look as well, since that one dims the panel based on room light and makes every calibration attempt a moving target.
Which brand hides this setting the deepest? My money is on the one that puts it three menus away from picture.
