I think as game assets are developed with it in mind the aesthetics will be fine.
The Grace example definitely changed her look by making it look like she has strong makeup on, but that was likely because the assets, when they were created, weren't tested with this technology.
If you look at the other examples, like Leon as an example, I think the aesthetic shift isn't as pronounced.
Edit: I hope Nvidia releases the option to use a second card for DLSS to consumers. Multi-GPU builds (outside niche lossless scaling use-cases) would be kind of cool.
