The form. The way it's facing up, not out. And it looks to be a much larger bloom with a looser habit. Some of my photos on this database are from the first season after planting too. Usually first year lilies might have paler coloring that would improve as they mature over the years but they don't change their habit or form.
Bulbs get mixed up sometimes from the suppliers. I've had some that didn't bloom true to name. It happens. Compare your photo to the others on here. They don't look alike. There is one other photo that looks wrong too. I've let them know as well.
