The way BG3 is structured though, you are not meeting enemies that you can't handle (exception would be the fight between the mindflayer and demon, but I've read someone beat the demon, right? and the other exception would be that you are not suposed to fight the dragon... but again, people kill him with the questionable game design decisions). Its a common trope to meet the arch nemesis before you can handle them. Or see challenging creatures that you avoid and come back later. None of this is though present in BG3. You just keep seeing the rarest creatures D&D can offer, you can even squish them if you like and you move on your quest with your ultra special friends... being level 4. Keepin in mind that once you finish a hub you have absolutely no reason to come back and in DOS2 you actually even couldn't from what I remember, so I don't think any content is meant to be 'kept for later'.
I have no problem with variaty to some degree. For example I'm fine with the goblins not being the standard D&D goblins (I'm not fine with the game design reasoning behind it, but I generally don't mind modifying enemies to fit the story). But as an example on that I didn't like where the two utterly random buffed up minotaurs that did nothing for the story or setting except whipe your party with an unexpected skill set. To me minotaurs are not the first monster that comes to mind in the Underdark, it just felt random and out of place.
At the end of the day, we can desect every single encounter on pros and cons why they are in there, but the result of all parts combined to me remains what I've said. Everything is special to the point that nothing feels special in this game. Sadly.
Regarding the level scaling and level displaying - it actually might just be a bug or unfinished part, since it looks ported from DOS2. So I wouldn't read too much into it, but who knows.
They may have overdone it - but it is not automatically problematic as it was originally put forward as. I liked that they managed to properly add in mindflayers to tell the story. I never tried to attack the dragons because I saw them as background as opposed to things I could kill - I have tried to kill the demon lord but horribly failed. I have not tried to go through the underdark as of yet wanting to try more things in the storyline before with different characters - but minotaurs do seem an odd placement.
