400 games are not enough to detect small progress so it is not clear that the answer is no but I dislike stockfish's design for elo and I consider to build rook odds rating list when 2 engines play without rook a1 and the winner is the engine that can win faster.
The question is if there are people who are interested to help to build that list.
I suspect that even some old stockfish before NNUE can perform better than stockfish developement version in the rook odd list.
