Except that's sort of not what Ultron is??? That statement is very contradictory of Ultron's characterization. Yes he hypes himself up as technological perfection, but part of his characterization is how his drive is deeply rooted to human emotions/psychology (he has an oedipus-complex in the comics for crying out loud) and often times that proves to be his biggest weakness (even Whedon recognizes this and blatantly mentions how Ultron is a very frustrated and angry A.I.) It's what makes Ultron so fun as an A.I. villain, he's NOT entirely logical, as a lot of his mentality is based on human irrationality, hence why he's so psychologically flawed in his schemes and design.
Even in Annihilation: Conquest he finally comes around and believes that humanity as organic lifeforms definitely has its uses contrary to what he used to believe, and he even believes that techno-organic lifeforms are far more superior than purely technological beings (the former being his end-goal in regards to what wants to become). If anything, going by Ultron's mentality, it should be the reverse: he starts out more mechanical and becomes more techno-organic (i.e. humanoid) by the end of the movie.
As for the productions shots, it may or may not be Ultron, but it's definitely very heavily Ultron-inspired. Anyone who's read Annihilation: Conquest should easily recognize that it's far closer to Ultron's design than a Hydra Dreadnought.
