I think the comparisons that Nvidia flashed out to demonstrate DLSS 5 itself is very clear that it is not just a matter of lighting. The face of the characters definitely got transformed in very obvious ways. This reminds me of those phone cameras that will use AI to detect the subject and make the photo seem nicer. For example, I tried using a Samsung phone to take a picture of the moon and it is clear the moon image that I see with my eyes is very different from what appears on the picture. Almost feels like it detects the subject and looks up for an image to replace (or what they call AI enhanced).
Regardless of the final looks, I do think the hardware requirement to get this working pretty much negates any benefits. Instead of making games run faster, DLSS 5 is making game look better at the cost of expensive hardware requirement. I do think it is not progression but rather regression for gaming. I am playing a game, not watching a movie or enjoying the scenery. Over time, I just find AI a waste of sand and resources.
