Diet Dr Pepper — Can vs. Fountain

Backstory: my stomach doesn’t like sucralose, but I have no issue with aspartame.

From what I can tell, the Diet Dr Pepper at McDonald’s contains aspartame and sucralose. However, my can of Diet Dr Pepper at home doesn’t list sucralose as an ingredient.

Is this accurate?

Just wondering if for some reason McDonald’s just hasn’t updated their ingredient list, or if they do make different formulations of the same drink for various venues.
