Not the same brand, but we had something very similar with a switch in the kitchen, which combined with not-perfectly-straight walls meant that the outer faceplate sat slightly proud of the switches that sat inside it. Long story short, we just left it.
Can't tell from your photo whether the plastic frame has got paint on it in place, and whether taking the front plate off and scraping that off might help? At least in giving a more uniform/clean line?
