It is 1000% better than DOS2. Words can't express how happy I am with having actual visual storytelling in BG3.
There's really no comparison. BG3 isn't perfect, but it does a decent job. Check out the DOS2 scene on the beach starting at 1:30. Compare that with the Astarion scene.
Well that is only to be expected given the advances in graphics technology since DOS was in development and I'm happy for you that it brings you pleasure. I'm probably in a minority here but I would rather the several glaring issues with the game were remedied over having glossy and at times unnecessary cinematics.
In some respects I don't think it's valid to make comparisons to DOS because this is a BG game and should ideally have no reference to DOS whatsoever, other than the obvious ones in being a fantasy RPG. They are different settings with different rulesets, art, etc. and that should be apparent in BG3.
