BG3 didn't do things much better. In fact, it is far worse than many other D&D video games at properly introducing many of its concepts.
Like, in Path of the Righteous, you have plenty of dialogue with Woljif and his entire backstory to explore the issues regarding Tieflings as a race. Yet BG3 provides absolutely no context as to why everyone are massive jerks to the Tieflings.
This new game should hopefully do a bit better in that regard, given statements about wanting the game to appeal to new fans who haven't played prior titles.
One thing that tends to help is the sort of thing that various games, such as Pillars of Eternity, do. Which is having key concepts that appear in dialogue being things that can be moused over to provide the information regarding it (As well as a Codex of some description that can be referenced to read about such things)
Such a thing allows newer players to get more information about the world, without awkward conversations where you're standing around in immediate peril and grilling someone on basic world concepts that everyone in the world should know, which is typical for plenty of games.
