Frankly I think that’s just recency bias. It’s new so it feels better. Before BG3 came out, most people agreed DA:O was the perfect CRPG, or Mass Effect, and just look at the sheer number of video essays on YouTube praising the quality of F:NV.

New games come along and old games look paltry in comparison. It doesn’t mean the older ones are actually worse. But you’ve had decades to enjoy DA:O, while BG3 still feels like it has secrets to uncover. It still is unexplored territory, and that’s exciting.

Personally I think that once the dust settles, it will be clear that, apart from limitations due to when each was made, these games are all equally 10/10 games in their own way. It’s not as though BG3 is without flaws. And it’s still actively being worked on.
