Didn’t the First Vision Reveal the True Nature of God?

A kind reader reached out to me and asked me to elaborate how my writings about the nature of God work with Joseph Smith's First Vision, since it seems that his vision was meant to "clear up the confusion" surrounding the nature of God, the prevailing idea that God "was not made with body, parts or passions." Wasn't "the point" of his vision to "define for the world who/what God was"?
