Yes, the apps perform better/faster and generally have more UI thought put into them. Overall, lower friction. Often when people need to use their banking app, they're in a hurry, maybe stressed (e.g. in line at a grocery store) so everything the bank can do quickly and with visual assurance helps.

On the premium end of banking, where users generally aren't stressed about money, offering an app is more about catering to however the user prefers to interact.
