I have the S95B which is last year's S90C and you do not need to exit whatever you are watching in order to tweak the display settings. Just hold down the microphone button on the remote control and say "Settings" in order to go directly there if you don't feel like clicking through any menus at all. Simple!
Here's one "big way" it loses: poor support. It may be a great TV. It may be the best TV right now. But Samsung will push an update that will break its functionality, then claim they know nothing about it and that there's nothing they can do about it. Planned obsolescence through software is part of the Samsung business model. If you want a television that works with your receiver, soundbar, or any other accessory for more than two years, steer clear of Samsung.
