Firstly, SPSM came BEFORE The Last Chakra Mode.

Second, The Last Chakra Mode is NOT apart of SPSM; it is Naruto's Kurama Mode + (normal) Sage Mode, only it is the version of chakra mode when BOTH halves of Kurama have been been put back together as one, and has been sealed inside Naruto. The first time this happened, was during his battle against Obito, and it was when Yang Kurama alone was sealed in Naruto. Also, FYI, according to Kishimoto, The Last IS canon to the story.

Third, the chakra modes we see today, in Gaiden & the Boruto franchise, look the way they do, because Naruto is NOT using his full power. He's only using Kuramas power along with his Six Paths power and natural energy. In order for Naruto to go full Six Paths Sage Mode: everything but his skin glowing, a full black bodysuit with a ring around his torso, and having Truth-Seeking Balls orbit behind his back, Naruto would have to tap into the power of ALL the nine tailed beasts along with natural energy and Six Paths power.
