score:2
As far as I can find, the only big-screen retransmission of Roland-Garros in Paris this year is in Roland-Garros itself. There's a large screen outside the venue. I didn't find anything else with a Google search in French and the article on the Paris municipality website doesn't mention anything. It looks like there's no Roland-Garros dans la ville program this year.
Plenty of bars and cafés are showing it on TV.
Tennis is popular in France (well, mostly Roland-Garros), but not as popular as football. This year the women's football world cup is being held in Paris, so tennis has to compete for attention and organization capacity.
