I'm afraid I can't remember the source, but I clearly remember an interviewer asking Bob Stuart about multichannel MQA for movies, and he replied with something along the lines of:

We don't think that will happen in the foreseeable future

From the context, I'm pretty sure he wasn't saying anything specific about multichannel MQA music, but I'm very sure I've never heard him refer to MQA and multichannel music in of the interviews I've seen or read.

So not a "no," but from what I've read/heard not remotely in the forefront of the initial rollout.
