Hardly. That is not the way that box office revenue works.
First of all, the film has an estimated adjusted budget of $410 million (~$250 for production and ~$160 million for marketing). Off the top, the move has only generated revenue amounting to twice its overall investment.
Second, there is the revenue share between theaters and studios. On average (each studio makes different contracts for different films), the share is ~55/45, with the studio getting the larger portion. So of the $897 million this film made, $410 million doesn't count because that is just the return on the initial investment.
The profitable portion of the revenue comes from the remaining $487 million, meaning the studio is only earning ~$267 million off of their $410 million investment. But even this is not an adequate overview, because the share taken by the studio is even smaller overseas (~40%) than the average I listed above. In other words, the actual revenue earned is likely less than $267 million.
So, no, the film is not a "smash hit". Warner Bros. will make their money though thanks to licensing and video sales. But making their money is not synonymous with "smash hit". This film would have needed to cross the $1 billion mark to have truly been a smash hit. As of right now, Warner Bros. is mostly in the position to break even, since the rule of thumb is that a film should earn twice its total production budget to break even. Batman v Superman narrowly earned more than twice its budget.
