I'm about 1800-2000 on lichess and have almost complete aphantasia and I do feel like it really hurts me, especially in very sharp middlegame positions. When calculating I have to explicitly list out what squares are attacked by what pieces, which is inevitably very slow. Long term positional planning isn't a problem as I can feel my way around a position pretty well and can imagine positions I want to reach, but detail heavy calculation is much harder. Doing a lot of deep puzzles is the best antidote I've found.(And blind chess, but that's really hard)
