as far as we know, Porphyry did not consider the divine intellect to be a hypostasis clearly distinct from the Soul, but he often designated it ‘hypercosmic soul’.
As Gregory of Nyssa had explained, the three hypostases of Father, Son, and Spirit were not objective facts but simply “terms that we use” to express the way in which the “unnameable and unspeakable” divine nature (ousia) adapts itself to the limitations of our human minds.
Physician: I have viewed your urine, and the hypostasis, / Thick and obscure, doth make the danger great.
When penetrance is suppressed altogether, the term ‘epistasis’ (and ‘hypostasis’ of the suppressed gene) is used.
