I mean they have eyes. They look at the results and decide they like it. Looking at this, I think it looks worse, but it’s not hugely different and I can easily believe it looking better in motion. (The picture in the body. The post-picture looks better in the version that has multiple colours, can’t tell if that’s new or old, but I doubt the technology chose to make it all blue on its own).
I don’t think the people at the top actually sit down and watch the entire process. They are just told it will make the picture “clearer” or “sharper” or “more up to date” or something, they’re wined and dined and constantly told how “advanced” this stuff is. If they’ve put a lot of money into “updating” something they’ve done, they probably don’t want to admit to themselves that they just wasted millions, they’ll focus on the positives of it, rather than the negatives.
