Also I can see that difference when the frame is fully equipped. In this condition, I can see that seatpost is going up to left side. I also uploaded three photos which I took the other day. Actually, there is no framebuilder near my city so I asked for some opinion for this.
All this speaks to is that the top ends of the two tubes are not parallel to each other. Not that the tubes' axis are off. Or that the I phone is not sitting flat
Again get both you and the bike to a pro. Andy.
