> Even better comparisons are in the blog post for a competing product: https://www.pixelmator.com/blog/2019/12/17/all-about-the-new... (likely the same algorithm, but using a different training set, so results will be different from what Adobes product does).

Aren't those comparisons misleading though? The ML sample is 4x the resolution, comparing to something that is supposed to be used to also make something 4x the resolution. They aren't upsampling the comparison, so I don't know what they're actually doing with it. It's so misleading I just assume the company is scummy.
