It did better than Tenet in most markets where it opened. It hasn't opened in China yet - though early user reviews from China seem to HATE the movie, so it's gonna be interesting to watch.
Disney+ isn't in all countries yet, so it doesn't necessarily have to do better than Tenet's WW, just hold the fort in the countries where D+ is available (and remember: WB gets 63% of the theatrical grosses in the US, whereas Disney gets ~100%, so they don't have to make as much money to get the same amount of revenue).
