Some years ago I had a teacher that got very mad because I played with the pinky like that, only in my RH. She told me to try to relax the finger, and I spent some time thinking about that while playing. It was uncomfortable, but after a month or so the pinky just went to the right position.
I think it's not bad as long as that position doesn't get in conflict with your performance. However I have never seen a video or a live performance where the performer plays like this.
Hope you can deal with this.
