When you go from SD to HD video it's hard to go back. Same again when you go to 4K. Same again when you start eating higher quality foods. Same again when you start driving nicer cars.

I'm sure there's a technical name for it, but for a significant number of people, once you get used to the higher quality it's harder and harder to go back down a level.

I would counter that once someone goes from a common, well engineered brand to a less common, expensive, and equally well engineered brand, they'd have a hard time going back. You only need to look at clothing brands to see this everywhere. Not all differences are functional in the way that you have drawn the comparison.

I disagree. It's all about adaptation. Sure, if you step down to SD from HD, it will be hard. But if you are forced to watch SD always, you will eventually adapt to it again.

And why would I ever want to do that? Sounds pointless when I don't have to.
