You can unlock the recollection room from the beginning but in order to see everything, you need to play through it.
Recommended to play through pure, saving at game over decisions and the Chapter 5 exploration (recollection room is missing these). Progress the dialogue with every FP and go to the park to train yourself for free levels. Take a look around town for events.
Right before the final chapter there's a point where you can just progress all the girls' NTR routes from the park.

There's also (actual) poop in NTR Rikka 5
Also, what's up with the sudden 3d models in Ch6 Defeat Hitomi?
