I hear what you are saying and don't want to argue, but with my year of raptor the engine revs higher before it changes gears in the transmission when in sport mode. For example it will not shift into the next gear and will hold the rpms at 3 to 4000 before shifting, while without being in any mode at all the transmission shifts into overdrive even at 1500rpm. C'mon, nobody????@CoronaRaptor Unless you have Offroad mode on, the transmission shifting is not affected. The "Street Sport" pertains only to the traction control. Shift points can, however, be affected by aggressiveness of throttle input. For example, the truck shifts as quickly as possible to the highest gear at light to moderate throttle while holding gears or downshifting during WOT. Only the 2015+ F-150's have an explicit sport mode that also affects transmission shifts in addition to traction control aggressiveness.
In short, I'm not arguing that you're noticing a difference, but the fact is that the sport mode you're referring to is 100% associated with the AdvanceTrac settings which ONLY control how your ABS, Yaw Control, and RSC work. So, the only "shifting" difference you may notice is the PCM not cutting engine power when detecting wheel slip as you're hooning around town or otherwise.
Hmmmm.....now I want to take her out of the garage and see
