[Question] Gym Control Bonus

Has anyone seen a Gym Control bonus yet? I'm pretty sure I haven't seen any, and I've done like 11 Raids, with at least a few at my team's gyms. I know for a fact that I have captured at least two or three gyms prior to doing the Raid (although on my screen the gym doesn't change color - but My 'mon is in it; it will change color for other people).

I've also likely (but cannot 100% confirm) Raided at a blue gym that was not change-team leading up to the Egg Hatching.

Just trying to see if this is glitched or I'm missing something.

Thanks!

Edit: To be clear - this is regarding the number of Premier Pokeballs you get at the end of defeating a Raid boss - i.e., the number of tries you get to throw at the Raid Boss Pokemon at the end.
