This is something I've been noticing for over a decade now. All western games use that completely forgettable, generic, orchestral style, and it's starting to affect Japanese games, too. A big part of it is the fact that boomers basically decided not to pass down anything their predecessors passed on to them, so everyone who came after doesn't even know the basics of the basics. It's not just music, either. The Last Jedi was a master class in awful writing for the same reason, and there's a picture of an article by a guy who had art students beg him to teach them the basics that they weren't being taught at their expensive university.
Thankfully, it's not all doom and gloom. Falcom is still around and still putting put that high energy music that used to be associated with Japanese games.
