Yes, does seem odd this data is not out there someplace. With this phono stage in production for so many years it is hardly an obscure circuit.
Sites that talk about "Miller Effect" in 12ax7 are all over the place on what the functional capacitance might be. Seems the topology/function of the gain stages have an impact on Miller Effect capacitance. None of the sites I can find discuss the 12ax7 in exactly the same circuit as the stock PAS phono with its negative and positive feedback.
I lack the gear to do this check on my own. Perhaps if I were more clever I could compute it.
