Cutting the number down

Store-demo picture modes are tuned for a showroom floor and can double the draw versus a normal viewing mode.
Automatic brightness limiting keeps a dark room from being lit at showroom levels, which is both cheaper and easier on the eyes.
A soundbar, console and streaming box left on add a standby load that never appears in the TV's own spec.
