It certainly extends to taste, I wouldn't be surprised if nutrition also. I don't think you can be as simplistic as "US chicken bad" though. The US has a very well established industrial food chain that reaches everywhere, but it's not the only thing going on. The US industry has some economies of scale that work for it too. Quick-cheap-and-nasty chicken in the UK is just as flavorless as in the US. And you can find better stuff in the US, albeit at higher cost. But the same can be said of flavorless but cheap Holstein milk & butter, or basically anything that has been subjected to aggressive optimizing for cost per unit/volume whatever. Applies to factory bred chickens, but also tomatoes designed to ship well. The end result is usually pretty cheap, and pretty bland at best.
