Probably a little, in the meaning that it probably covers the "re-imagined" things of an older generation put in a new one. Since they seem to be going on a different route with remakes compared to the past, I think that when looking at new remakes the actual ones will be pretty similar to the older games, while the Legends series brings the innovative part. I would say that it kinda is like the Delta Episode was for ORAS. But can it be considered a remake? Not at all indeed. Especially considering that it's only Lumiose city and not the whole Kalos, as it was mentioned.
