You've missed the most crusial aspect of the SPSM you've cited yourself: "The one consistent hallmark of Six Paths Sage Mode are Naruto's eyes: his eyes are yellow, his pupils are a cross of vertical fox-slits with horizontal toad-slats, and there is no pigmentation around his eyes that would otherwise signify standard Sage Mode".

In Boruto movie, Naruto displayed both the cross pupils and no pigmentation. So it's SPSM he used. Regardless how drastical his chakra mode can change, the SPSM itself is displayed only by the eyes. So he did use SPSM in the movie. Period.
