Did you watch the video where she demonstrated how the technology works and how she says it differs from photoshopping? She pretty clearly explains the difference.
It’s a computer changing colored pixels, it’s marketing fluff to try and say it’s not the same. Especially the concept that these things will really look that way on dry land, I can assure you they would not.
Again, did you watch the video? The technology is different. Yes, it involves a computer changing colored pixels but that's only one part of it. The calibration process is something you cannot do in Photoshop. Photoshop does not place physical color calibration charts in the sea and calculate the color profiles for you based on that chart.
