The "yellow skin", as it was addressed numerous of times before, has nothing to do with SPSM.

In the same way Naruto combined SM and Kurama's chakra to obtain KSM, he combined SPSM and Kurama's chakra to obtain SPSM.

When Naruto hit Madara with the lava release rasenshuriken, that was the real SPSM. The yellow cloak, regardless if it was the one from the war or the one he uses now, is just Kurama's chakra. Nothing more, nothing less.
