Do you have any examples? I'm not much of an in-game flirter so I haven't noticed. Just more flirty dialogue before the romance scenes itself?
Yes. You used to have like no options at all. Just suddenly everyone wants to BE with you on that one night.
Example I just had was Astarion staring up at the stars. During the convo, several options to suggest that you'd like to get to know him more, enjoy his company, travel together even after it's all over.
I know Shadowheart has a few more now as well, and I even saw one with Lae'zel, getting to know her more with her discussion about the Tears of Selune. It's like 10 times better. I feel like I'm actually getting to know the characters more.
