I think that's been upscaled, as it shows Neptune being over 300px in diameter. Unless I'm misinterpreting something (a distinct possibility), that would require an angular resolution of nearly 10x what the JWST is capable of. I don't know what kind of processing they applied to get it to that size but I can't resolve any detail in that closeup that isn't visible in the version where it's 80px. By my naive calculations (which I explain in another comment), Neptune should be about 30 pixels wide - is there anyone who can shed light on this mystery?
