I noticed that it is ON with a YCbCr signal
and a RGB
full range signal, but that it's OFF with a RGB
limited range signal.
I mainly turn it on (aka switch to Standard mode), when the the room lighting is
very dim and controlled and I want a little extra blacks, which is mainly for gaming. It's sort of like a fun effect when you turn off a flashlight in a dark room and it gets very black.
Basically Instead of having a day calibration and a night calibration with different backlight settings I just toggle motion lighting for the dark nighttime viewing where you would normally anyways already calibrate and lower the backlight for that room.
I would recommened leaving it off when your room lighting isn't controlled and
very dim, or during the day. In those cases you can't really see any benefit to the blacks by lowering the backlight, but you can see the picture get dimmer.
