It's not that the Rasengan is not made of sand, it's that the color of the rasengan isn't changed to suit Naruto's new chakra, like what The Last did. Also the SPSM is apparently more stable than previous forms due to the lack of flames in its manga portrayal (that could be Kishi being lazy though, idk), so it'd make sense for the aura to be a mere glow, similar to how the opening portrays it.

Also yeah I'm looking forward to next week's ep. I hope they can handle all the calamity going on instead of butchering it for time and budget.
