Maybe. But tracking has gotten really good over the last decade. And the whole Barbenhiemer phenomenon (which greatly increased the overall awareness of the movie, as well as the desire to see it) was the primary driving factor behind the increase in the tracking numbers that saw amazing growth in the past three weeks.
There's actually been a fair amount of discourse in the industry about this, and why this type of unexpected viral phenomenon matters; I don't think anyone genuinely thinks the Minions: The Rise of Gru was the greatest movie in the history of ever (6.5 IMDB, 70% rotten tomatoes), yet the unexpected Gentle Minions phenomenon was certainly a major factor in the box office performance and caused it to significantly overperform expected numbers.
In other words, sure, it's a great Nolan movie. But it's also a biopic about a figure most people aren't familiar with. The gangbuster box office for opening weekend (as well as the many reports of theaters being fully sold out) is a reflection of the pop culture zeitgeist.
