Nope. Only bloomed girl with a 3rd portrait have a new scene. Bloomed girls with power only (on DMM, to be faster with blooming process, they add 4 or more girls + new girls bloomed form with only power and boosts) and girls without bloomed form don't have new scene.But all girls still got stats boosts from 2nd affection.
