s6 edge + camera port?

as you know, the s6 edge + is here. its just like the s6 edge but bigger. theres a new cool feature to the edge - another line that is app launcher.
but the coolest and most important upgrade is the camera new feature - shutter speed!
my question is.. is it possible to port this feature to s6 edge? or is it ONLY depends on hardware capability?
i mean does this feature on the s6E+ only because of the hardware camera? or is it only a software addon?
