I wonder how these differences extend to nutritional value?

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.
(A) The terroir for wine is probably the pickiest of all mass produced fruit, at least according to White’s Understanding Vineyard Soils.
(B) The soil of the Western US is extremely varied but it’s hardly the only factor involved in the taste and cultivation of fruit. The most obvious wildly differing factor is climate. The high deserts of E. Oregon would produce very different fruit compared to Washington’s coastal region even if you used identical soil, due to rainfall, mean/median temps, diurnal temp variation, etc.
However I suspect it's especially bad in the US as the video did casually mention battery cages were made illegal in the EU. Furthermore, that chicken farm was a lot less crowded than some of the Purdue farms filmed in activist videos.
