There's definitely something to this: I spent most of the last 15 years in Italy, where people care about their food. They care a lot , and will absolutely discriminate between various tomatoes based on where they're grown, different kinds of pasta, and many other things to boot. In the US, I think we tend to just look at the price and mostly go by that if the product is not clearly awful. It is changing though: it's…
I find higher quality food to be a case of rapidly diminishing returns. When I'm cooking for myself, occasionally I'll take the time to make everything from scratch with fresh ingredients and it will be nicer, but it's only 10-20% nicer (if that can be quantified) for several times more effort.
I find some things I don't notice as much difference (cream, butter) as I will others (milk, eggs)... There are other things that are a matter of taste (grain, grass, grass-finished beef). I wish, for that matter, that more labels contained what they were fed especially for milk and eggs, as the difference between brands/containers and locations is huge.
I try to cook at least once a week, and sometimes that means spending a day making broth/stock (mushroom is an absolute fav, but the most expensive where I live). I find that there are just a few things that make a huge difference, and others not as much... others still are a matter of preference. I also find that mouth feel is as personal as anything else in terms of enjoying a particular food.
