Here's what Google has to say about the one in their pixel 8.
"If you’re trying to take a group photo, even if you take multiple shots, chances are someone is always looking away or blinking — we’ve all been there, especially if you’ve ever tried to take a photo with kids. To take the stress out of getting that perfect group shot, the new Best Take feature in Google Photos uses a series of similar photos taken close together to help you automatically create a blended image with everyone’s best expression."
Probably William took several photos and then some button popped up saying something like 'enhance' which did that.

In my case, I just composited together a handful of the very similar shots into one photo in which everyone's eyes were open, looking at the lens, etc. Because kids can't not fidget, especially when asked to hold a pose, the registration between almost identical photos taken seconds apart is often not perfect. I'm certainly no royal watcher but for a self-posted social media photo (vs some official press or journalistic photo), this seems like a pretty reasonable thing to do, if only to spare the kids a stressful experience from which they are likely to develop resentment toward official PR duties.
Applying Occam's razor, I think this explanation is far more likely than some nefarious palace scheme (in which case, I'd expect the composite to be expertly done). The fact the composite is imperfect supports the idea it was done fairly quickly by one of the parents or one of their non-expert personal assistants and not carefully reviewed by a cabal of master media manipulators orchestrating some conspiracy.

The Princess of Wales has apologised "for any confusion" her Mother's Day photograph caused, after five agencies retracted it over editing concerns.
Catherine, in a statement posted on Kensington Palace social media, said: "Like many amateur photographers, I do occasionally experiment with editing."
The image, taken by the Prince of Wales, was the first of Catherine to be released since her surgery in January.Virtually the only original parts of the image that are unmodified are the faces and hair from the neck up and fingers on the two older children. The person who made this clearly had nothing to go on.

“I cannot emphasize enough how out of character it is that a royal press team went on the record in response to what is essentially gossip.”The (soapy) speculation is that Kate is either ill, dead, or missing for some other reason.
It is quite strange to post - and then have to kill - a montage with obvious flaws when a real photo should have been so much easier.
