Oddly, our experience contradicts this: Buster (Persian) could *only* eat President's Choice "Finicky Cat Dry Cat Food - pH Control and Low Magnesium
Any change at all in his diet (except for the odd little bit of canned food that included turkey - he'd snub anything else) would result in crystals and a round of antibiotics.
I think it would be more accurate to say, it's not so much about whether a food is "premium", or specifically about the "quality" of the ingredients, or the form they take... but how your specific cat's body handles a specific food.
What's true for one may not be true for the next.
