As an American, I do indeed have little idea what sorts of improvements people in the EU as a whole - much less any individual country - have had. I can guess at a few, since presumably a lot of my items transfer. (Pascalization for avocado preservation, for example, is presumably a world-wide thing because the laws of physics are the same everywhere.) But I can't write a decent list.

I see that fact as more of an invitation to write your own. Do Europeans feel annoyed at the omissions of XYZ? Go right ahead and make your own! There's no patent on the idea of 'writing down a list of things that have gotten better'. I'm not going to sue you if you write down a list of ordinary things that have gotten nicer in the UK. In fact, I'd be happy to link it in the external links section if anyone makes a decent list for some other country in the same spirit. (I would prefer it not be tech-heavy, though. Things like "did you know PCs and smartphones also got really cheap in the Third World or the EU, and SSDs are pretty sweet compared to HDDs?" are not particularly interesting to anyone and do not need to be pointed out.)
