Imo, it's the reverse. Beat gained more of a personality once she became a Cure and Amour gained less. Aside from the stuff with her father. All she really did was sing and eat food. The show itself tried to compare her and Emiru's relationship to that of Nagisa and Honoka. But, there's a big gap between those 2 pairs even if you look at them from their finales.

Beat continued to be the silly person she always was. Just that now that silliness moved from her villianous schemes to her lesser understanding of how things work in the human world.
