I rather think that the HolySpirit has not ever been `seen` and cannot be `seen`. The fact that He is omnipresent means that there are no edges to His form. Without edges a thing cannot be distinguished. There must be something next to it with which to contrast it.
Jesus revealed the HolySpirit by operating in the HolySpirit, speaking His words and doing His works.
Jesus is SpiritSoulAndBody.
Jesus` Spirit is the HolySpirit who gave birth to Him. Jesus is the manifestation of the HolySpirit and so He, in a sense, is His own Father.
Jesus` HolySpirit begat His body and fills Him, and crowns Him and manifests Himself (HolySpirit) physically in Jesus.
Being in the bosom of the Father speaks to the Soul and Body of Jesus resting in His own HolySpirit.
