Game of Life - Board position and Paul Morphy

There is an painting "Checkmate" that depicts Satan playing against a young man. The board position is supposed to appear hopeless but it is said that Paul Morphy when seeing the painting studied the picture, called for a chess board to be set up and some time after declared the young man has not yet lost, and that Paul Morphy could win the position of white.

Here is the original painting

Here is an picture of the someone trying to diagram this picture

I have some doubts about this because the painting shows black King on d8, but in the diagram above the black King is clearly on e8. This was debated with surprising politeness in 1888, see the discussion here. I put this into a chess engine Houdini/Stockfish.
