From the thread title, I really didn't expect this to be a legitimate grievance, and almost didn't click it... But comparing the two images, I do think post #7583414 has detail that post #7583372 doesn't. I will appeal it accordingly.
The post noted has more detail than the AVIF parent, as I see it. Look for example at the blush lines below her eyes, which in the JPEG extend farther and are sharper. More generally, a bunch of fine lines in the deleted post are blurred or slightly misshapen in the parent. The AVIF is over-smoothed and that's just less obvious than JPEG artifacts IMO -- probably both because AVIF is designed to have less noticeable artifacts and because we have experience recognizing JPEG ones.
However, the colors seem a bit better on the AVIF, which suggests to me that neither one is the true original. I'm not at all familiar with pixellent.me and gallery-dl has nothing but it's possible there's a better way to get original images from there.
