It's curving up WAY too fast at the end, that is very far from an ideal design. Expect little improvement if any.

Second question: I know this 'functional' roof spoiler has helped the Lancer Evo IX MR by generating extra downforce to the spoiler. I was wondering, how effective will this thing be on a factory BRZ spoiler or will we have to find a big aftermarket wing like the Tommy Kaira to make this roof spoiler effective?

First of all, learn your terminology, that's not a spoiler, it's a row of vortex generators. It would be useless on this car because the stock spoiler is near the "ideal" position and airflow is mostly attached on the back glass.
