You don't need mega- hardware, if you go 4 moves forward with Stockfish. (or only three, if the point of reaching 8th rank with the b-Pawn has arrived sooner)
Then it "sees" the underpromotion at high depthes (about 75), which yet are reached in a few minutes.

Great study, thanks for bringing it here
Peter.

I have not tried the unmodified one, but a modified Stockfish still does not see a minorpromotion to Rook in PV at depth 92. Not my best version but I thought it should see it. It reaches big depths; 49 plies in just one second but PV is not as good as the reached depths suggest. Does SF get enough depth from the study position itself (minorpromotion just being a sideline in PV)? I suppose Peter has tried it. But probably not every SF in the past see this from study position?

"+128.xx" indicates a tablebase win, it's not a mate score; I believe we've gone over this already.

You are correct it's 17 ply from hitting an EGTB mate - so it's not a mate-xx score that is correct - but it does represent a certain mate in the not distant future - so for the uninformed, saying "mate score" indicates certain mate which is what I meant by saying mate score. It is more accurate is to say it is a tablebase win. I prefer to say it's a mate score.
