I think you've hit the nail on the head when you say the visual energy of the movie is being changed. This kind of post facto alteration of movies has really come to drive me nuts. Initially it seemed to be part of the move to get a preferred cut of Blade Runner, of Pat Gareett & Billy the Kid, and some other films of the like, but I think a distinction has to be drawn between the movies marred by studio interference––Blade Runner, Pat Garrett––and ones where the filmmaker changed things after later consideration, but basically got what they wanted in the first place––Star Wars, Miami Vice, Mad Detective, Fallen Angels. These are films that played one way, and then received after-the-fact modifications that went so far as to exclude the opportunity to see it in its original form. Of course, Mad Detective has the inferior-quality Mei Ah blu ray in its original cut, Miami Vice has the Theatrical Cut blu ray from France, Star Wars has a lot of fans pitching together to do their own restorations to what the films originally were. As for Fallen Angels, at least the AE disc is still available, but neither that nor the Kino are anywhere near what the picture quality will end up being on the Criterion disc. And this reframing will be just petty enough, for a film with much more limited interest, that there won't be some fan edit where the stretched footage is visually reformatted to make a better-quality fanedit. This will just be the way the movie is now.
I guess I feel like these "director returns to make what they really wanted to make later" cuts of these films are usually made from a very different mindset, and they choices that get put in there don't really add up that often. In the case of Apocalypse Now Redux, I do think the film has been really carefully reconceptualized, without losing the stuff that worked so well in the theatrical version––and Coppola has been pretty fastidious about keeping each version available, each in high quality. That's something I've greatly appreciated, more that Michael Mann's and WKW's sotto-voce tinkering behind the scenes. That international cut of Mad Detective––which has now become the main way to see the movie––takes it from "magical-realist detective movie" to the much duller "police procedural with a big plot hole created in the edit." I had loved Miami Vice in theaters, got to appreciate the director's cut blu ray, and then finally saw the theatrical presentation on the French blu ray again and realized what Mann had taken away from my viewing experience. Obviously, these are worse eviscerations on a narrative level than what presumably will happen to Fallen Angels, but...I am very, very sensitive to film being stretched or squished. I watched the trailer on a small Vimeo screen, and I could see it happening right before my eyes, and it looked...all kinds of wrong. I wish there were to be the two versions of the film on this disc, but I feel fairly certain there will be only the one version.
re: Ashes of Time, that's the World Video edition, which is cropped and then the image is moved to the top of the screen. Visually it is not as good as the Mei Ah DVD (also from Hong Kong, but released a little later). I've never heard of a Chinese edition. I have the Mei Ah and a TF1 disc from France, which presents an international cut of the film, but the picture quality is better than the Hong Kong discs. Here's a link to the Mei Ah edition:

I think this is the Chinese edition:
