It wouldn't really have an impact. It was honestly just the result of a phenomenally unlucky roll (since you roll Warp Phenomenon on a roll of a 9, while the bonus +20 to Warp Phenomenon from your psyker class means you ended up going right onto the Perils table). There's a chance you'd have cast the ability with no problems even if you had miscast.
