No you are confused. In order for Naruto to have the TSB he requires ALL the affinities + Six Paths chakra. But he can only USE those affinities when he access the chakra of ALL the Tailed Beasts. SPSM at it's core is this:

Yellow eyes, cross pupils(similar to Sage Kurama Mode) without the orange pigmentation. This form is able to TOUCH the TSB(you saw this when he kicked Madara's TSB away from killing Gai).

What Naruto uses in Boruto the Movie is SPSM but using ONLY Kurama's chakra. He doesn't form the TSB's because he isn't accessing his other chakra affinities that only he can get from all the Tailed Beasts.
