Might as well leave it and see how it does / ages. If the quality shows to not be very good, I'd recommend the self-healing Kavaca PPF from CeramicPro. My Supra is having it done as we speak...I'll post up once it's completed.
You'll likely find that the edges of the film will catch dirt and grime and will be noticeable as time goes on. No matter how hard you try to clean it, you can't remove the dirt on the edges.
At least you have something now that will provide protection. If the look bothers you now, you should look into replacing the OEM film. Otherwise, leave it on for now and replace it when you really start to dislike it.
