Does Lichess check for this? I definitely get an aborted game more often when I am white. I also notice my ELO went up after I actually locked down strategies for black. Yeah it’s only like a 0.5% advantage for the masters, but if you play a lot of games, aborting everytime you are black is a helpful strategy.🤷

Apparently it’s more like a 5% advantage for us normies. https://en.m.wikipedia.org/wiki/First-move_advantage_in_chess
