TaylorMade Superfast 48 3w/5w Shaft Vs Tm Matrix Ozik XCon 4.8 3w/5w Shaft Differences

[PND]

After years of playing a set of TM Burner Superfast Driver, 3W, and 5W, I was amazed when I recently realized that the Driver and 3W have a TM Superfast 48 shaft, while the 5W has a TM Matrix Ozik XCon 4.8 shaft.  They all look identical except for this label on the underside of the shaft, while the top labels all say Burner.  They are all regular flex, and quite honestly, I have never noticed a difference in playability. 

I was just curious if these shafts are basically the same and merely have a different label on them, or if they actually have different characteristics.  Again, I would never have known any difference by hitting them, and am just curious.  I am most amazed that I never noticed this in all these years that I have had them.

Guessing here slightly but feel pretty confident that it's the same shaft, just two different paint jobs. Fact that they are both 48g makes it pretty certain in my mind.
