It is now known that the $\infty$-category of $\infty$-operads as defined by Lurie is equivalent to the underlying $\infty$-category of the model category of simplicial operads, see http://arxiv.org/pdf/1606.03826.pdf. However, the proof in loc. cit. is obtained via a zig-zag of Quillen equivalences (going through Moerdijk and Weiss's theory of dendroidal sets and their variants, and Barwick's theory of perfect operator categories), making the direct comparison somewhat non-explicit. On the other hand, given a fibrant simplicial operad, we may associate to it very explicitly an $\infty$-operad, namely, its *operadic nerve*, as described in section 2.1.1 of Higher Algebra. The operadic nerve functor is not just explicit, it is also the one used in various works relating algebras over simplicial operads and algebras over $\infty$-operads, as in here. Being quite a natural construction, it seems very likely that the operadic nerve functor is actually the one that induces the equivalence above between simplicial operads and $\infty$-operads. Since the theory of $\infty$-operads has no self automorphisms (see here), this is the same as just saying that the operadic nerve induces *an* equivalence. However, since it is neither a left nor a right Quillen functor, it might be more accessible to tackle the question by comparing it to some zig zag of Quillen equivalences. Either way, my question is:

Is the operadic nerve functor an equivalence of $\infty$-categories?
