Totally agreed. I read somewhere that the only place these features help is sports. They should not be defaults. They make shows and films look like total crap.
These settings are the television equivalent of clickbait. They are there to get people to say "Oh, wow!" at the store and buy it. And, just like clickbait, once they have what they clicked on, the experience ranges from lackluster and distorted to being scammed.
Most people have absolutely no idea what goes into making the pixels on their screens flicker with quality content.
This way, you should not need to change them unless you want nonstandard settings for whatever reason.
