Yeah, no. They are two different rating systems (not ELO incidentally) with different curves, there isn't a fixed difference you can apply. At the high end of the scale lichess ratings are below, not above, chess.com ratings. E.g. Magnus Carlsen is 3131 blitz on lichess [0], 3294 blitz on chess.com [1].
This website [2] tries to translate between the sites, and figures that a 2925 lichess blitz rating (the closet on the website to the one reported in the paper of 2895) translates to 3000 chess.com.

Cool, thanks for the information! I did not realize the curves were that different.
3000 definitely bumps it up but it would still be worse than the top humans. stockfish is better by a lot.
Elo. Not acronym, named for its inventor Arpad Emmerich Elo
