It is amusing now that you point it out. There are always trends that come and go in these large scale industrial artforms. As others point out in this case likely a response to technical advancements and desire to emphasize those. Another example that would come to mind here is is the orangey-sunlit ears that seemed to show up everywhere to show off subsurface scattering.

Thinking back - films also are always doing some new exciting thing all at once. That wild colored lighting aesthetic of the past decade comes to mind. That's a result of refined color correction software and awesome low-cost LED lights. Or drone shots. So many drone shots.

It's usually a group-think phenomenon where everyone was previously unable to do something and now they can and everyone wants to try it. And then there are successes and management points at those and yells 'we want that, do that!', and distribution follows, and if becomes mandatory. Until everyone is rolling their eyes and excited about another new thing.

It's a silly phenomenon when you think about it - any true artist-director would likely push back on that with a coherent vision.
