Used wrong grout for repair (unsanded, slightly diff color) - will it be functional?

I screwed up. I have a million things going on and tried to repair a crack in my shower floor grout (2”x2” tiles). I used the grout I had - the lines are very narrow so I assumed it was unsanded - well, I think it was sanded. Also the repair grout is white and I guess the existing is “praline”
