I do not believe that tablebases make big difference.
I guess that Aristarch was simply lucky  in the first match and unlucky in the
second match.

For now
Jonny-Movei at 20 minutes per game 6-6

In the last 2 games Jonny showed poor play in the endgame.
In one game it allowed draw by repetition in a position with 2 pawn advantage
and in the second game it lost endgame with opposite colour bishops that it
evaluated as +1 for itself because it overevaluated some passed pawns
