I zoomed in, and saw a number of what looks like digital processing artifacts in the image. I asked a question about it on a Reddit post for a YouTube video, but I haven't gotten feedback yet. If those artifacts are from processing, uploading, me downloading it...

Based on a reaction video I watched from somebody who apparently follows the NASA team closely, along with a community of people who interact via Discord, the team was genuinely surprised and happy about the quality. I think you're in sound territory to hope it's true.

I love the selfie idea too! Really cool to see the 18 pieces of the mirror aligned so well.
