I started following yesterday this development, I have no much time recently.
About your question. First, to define perfect chess. Say, perfect chess in the sense of non-swindling or fooling around, 32-men tablebases.
I had a wide range of estimates, from 3700-4500 CCRL 40/40 rating points, and with the latest data of Andreas Strangmüller tipping to the lower bound, say 3800.
With this result, +28 =72 -0 (is it correct, or I missed some more results?), the tip is again towards a low bound in ELO. a +36 =56 -8 result would tip towards a higher ELO bound, although the ELO advantage of AlphaZero would have been the same over SF8.
It seems both these monsters play very often perfect moves, and sometimes maybe even perfect games. So, it seems the ELO bound cannot be very far away.
