Well yes, but he also downsampled the image to 170x170. As far as I know, downsampled information is strictly lost, and unrecoverable without an external information source (like an AI model trained with pictures of moon).
I'm too lazy to downscale it myself, so here's a 180x180 picture of the moon from WP [1]. This looks about the same as the Samsung result [2]. They are not getting the original detail, but they are getting the detail they should expect if Samsung simply deconvolved the blurred image.
