Yes, I recently did a BIAB Kolsch, and it was nice and clear.
Wort was clear/clean...no different than my 3v days. Beer was see through @ finished product.
Edit: & I BIAB no sparge (recent convert).
No sparge efficiency is comparable...if not better in some cases, and any differences are negligible either way.
It just goes back to what works for the individual brewer.
I prefer BIAB, but that's me.
