If they feel it's really awful they would lift it on the day similar to Cats and Rise of Skywalker (I think), same with social embargo. 2 days is standard practice for WB, remember Apocyalypse lifted a month earlier with 40% RT.
Aquaman and JL both had about 2 days gap, Aquaman killed it in China, and Joker got the push with the golden lion win. Heck, even SS got trashed but made 745M without China, it just depends on how the audience react.
And lol at the Shazam comment, it was brilliant on RT then nobody showed up.
Just an instinct, but South America will give this one a big push. Taiwan and HK will take a hit though, some will choose to stay home amidst the SARI attack, tho not huge markets anyway
