Hard to say from that angle. Usually you'd see cracked paint. Try measuring
the width of the slot in the seat lug at the top and bottom to see if
there's a significant difference (more than 0.2 mm because it it will be
narrower at the top once the clearance has been taken up).

I got rid of of the original low quality seat post and clamp on my Jeunet gaspipe track bike and replaced it with a SR Laprade post which I had to machine down to 26.4 to make it fit. I probably measured the original seatpost to come up with that diameter.
