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).
It has comparisons with nearest neighbor, bilinear and Lanczos filters and uses a slider to make it easier to see the difference.
