I think the narration allows some really interesting things to happen and is integral to the manipulation aspect of Baldur's gate 3.
To give an example - when you are dealing with True Soul Edwin, after he dies you see the tadpole. The narrator describes your feelings for this obviously disgusting alien worm, and one of the feelings you end up having is "compassion"...and then a few seconds later the narration questions that feeling "Compassion?". Then you have to make saving throws against its ability to influence your mind.
There is also something called an "Unreliable Narrator" - that Larian is playing with when they explore these emotional manipulations. Personally I am a huge fan of this style, a good example would be the book - We have Always Lived in the Castle - by Shirley Jackson
Also the narration is - as has been mentioned - descriptive and NOT explanatory UNLESS you make an appropriate saving throw - Arcana, History, religion, Insight, Investigation - and then you get an extra tidbit of info. This is exactly how actual D&D works. The "do I know this information or recognize these creatures?" Questions are quite common and the DM will ask you to Roll X.
Frankly I love the system and think its quite well implemented.
As for actual exposition, most of that is restricted to the books you find. The visual narrative "show, don't tell" is very strong in bg3.
If you want an example of actual bad exposition, go check out Tides of Numenera - worst written game ever, just from a technical perspective the exposition is constant and pointless. Pure garbage.
Although I have no idea how all this fancy literary stuff translates into other languages. I don't want to assume it makes sense.
