The version in Boruto clearly has the Susanoo armor on top of Kurama's eyes plus a second set. the Biju Susanoo only has one eye set as part of the armor. Besides, the humanoid isn't part of the Susanoo, it's the combined Biju chakra that the Susanoo acts as a vessel for. Note that Kurama takes up a similar position in the armor as the humanoid.

Secondly, Sasuke's Biju Susanoo and his Perfect Susanoo already share many similarities. This includes the main body armor. Note that in Boruto, Kurama is holding a solid sword, whereas the Biju Susanoo holds a lightning sword and the Majestic Susanoo holds a plated sword.

Seems to me that Sasuke just got better at casting a proper susanoo on to of Kurama. Note that the Boruto-era Majestic Susanoo shares similarities to Madara's, with Kurama's face exposed rather than covered and blades of pure energy rather than the plated form of Majestic Susanoo. (ch621)
