You're confusing resolution with models and lighting, which are pretty much the same between platforms.
You posted two screenshots of two different locations for what purpose exactly? When people say GF reuse stuff and don't make enough new, they're referring to Pokemon models and animations most of the time. What's the point in posting two screenshots of different locations in different games? What kind of comparison is that?
Of corse they're different, SwSh aren't just remastered XY. Don't misinterpret what people actually have problems with. I sincerely hope you're not trolling with these kinds of "comparisons". If we're talking comparisons, why don't you compare SwSh to other Nintendo first party (or even second party) games?
Thing is, exaggerations aren't lies. They exist exactly to make a point more clear by exaggerating the issue.
