Hm... apart from the very basic fundamentals, which is normal as each studio has a certain style and mark with their games, I can't say that at any point through playing BG3 did I feel like it reminded me of DOS2.

Now you could say that in relation to DOS2;

  • Nautiloid = Merryweather
  • Beach = Fort Joy Beach
  • Astarion = Sebille
  • Tadpole = Source
  • And so on...

But as someone who played DOS2 religiously for a long time, I can't say the experience of it ever poured into BG3 and made me reminisce. To me the experiences are vastly different, it's like comparing the moon and the sun. Yes they both share the sky and stars, but are nothing alike.
