The first picture is very hard to spot imo. I had to zoom in a bit to spot it initially. You'll see the "blockiness" is slightly worse in the webp version. (Left side of the image, head height) For the second image, I opened the jpeg 90 [1] and webp 90 [2] versions. Comparing those two, there are clear banding issues to the right of the neck. Slightly less visible are the darker bands circling around the whole image, though still noticeable if you know where to look. Comparing the jpeg 90 version with either webp lossless, jpeg 100 or jpeg 95, I can spot some very slight banding in the jpeg 90 version just to the right of the neck. Very difficult to spot though without zooming in.
