I'd read wikipedia's "One morning, after Johnny refers to Gheorghe yet again as a "gypsy," Gheorghe tackles him to the ground and warns Johnny not to speak that way to him again." as leaving it open. All the other references are to "migrant worker", which doesn't imply gypsy over here. There seems to be room to interpret it either way.

The Romanian thing over here is complicated, but ties in to anti-gypsy feelings and the right-wing press (Daily Hate Mail in the main) running any story they can find about Romanian criminal behaviour, especially if the perpetrator was Romani (or can be implied to be). Nigel Farage has slipped once or twice and made it clear that when he talks about wanting to ban European immigrants he's talking about those dirty Romanians, not those nice, clean, industrious Germans https://www.bbc.co.uk/news/uk-politics-27474099
