True but I it does give an idea that at F1.8 there is definitely coma. Perhaps not enough to be a big issue. I suspect the coma could be corrected with the distortion slider in Lightroom. My Zeiss Batis 25 looks a bit like that wide open at F2 but it corrects in Lightroom.
But for $2000 is that bit extra worth it? Irix 15mm F2.4 was my ultimate choice as best bang for your buck and look at a Sigma 14mm up the track when its price comes way down. Samyang 14mm f2.8 quality control is too poor so whilst good copies exist it seems for every good copy there are 2 or 3 bad ones.
