Everything about the look belongs to WotC. For example, the look of the city is based on WotC artwork. From a legal perspective, everything about the appearance of BG3 belongs to WotC.
The art for the city is hardly unique. But again, I'm not talking specific digital items. Many games share similar character design builders for example and there are only so many ways to represent a longsword. But what you're saying is that if I use ingredients similar to a high end restaurant that it will be pretty much the same - that's what I'm talking about. It's how it all fits together. A lot of people can use oil based paints to make a portrait, very few are Rembrandt.
Visuals could be quite similar and all AAA games are going to have visual appeal. That's only one small part of the picture.
