It appears that the flange is still below the surface of the tile all around. If so, the toilet should fit. Hassle is, the flange isn't supported. It is designed to sit on top of the finished floor, so height should be okay.You need to do something to support the flange rim, and then screw it down into the subflooring. It would have been better to tile under it, but you can't do that now without great pains.
