On Similar note, I have found that with 1511 - for Sales Order only 3 out of 14 FIORI apps are available in 1511 FPS1. (We are yet to TEST and see the actual working of these three FIORI apps.
We are yet trying to set-up FIORI Apps - we implemented RDS, however FIORI apps are not "auto-activated" and set-up with RDS.
So in short, Yes many FIORI apps not yet released in 1511 ..
I suggest, please check and confirm, if E2E the process can be run using GUI & then check the FIORI apps.
