I mean… yes, but this is kinda true for everything. Most people don’t change their worldview/religion/political ideology etc. when they’re happy and everything goes well. Most people also don’t start their own business, move countries or leave their spouse if they’re entirely happy with how things have been going.

To put it in system dynamics terms, in order for a system to settle on a new attractor state, there first needs to be enough instability to spur change. So the mechanism you’re describing isn’t unique to religion.
