Now audio uses open codecs for the part and new video will to.

That is because Audio Encoding hasn't seen much improvement as compared to video.

Nearly 30 years after MP3, the only audio codec that could rivals mp3 at the standard rate of 128kbps at a significant lower bitrate was Opus at 96Kbps.

And MP3 is still by far the most popular codec due to compatibility reason.

This is similar to JPEG, although things are about to change.

AAC and Vorbis were doing this for years before Opus was on the scene. Opus is a further improvement on audio codecs, but not an unprecedented one.

Opus and vorbis have both improved on mp3, flac has improved in the lossless space, and there are other codecs that do better at very low bitrates (think 20-30 kbps).

I don't have the Netflix / Disney+ / etc containers to analyze but Youtube has pretty much totally purged mp3 from every video on the site. Billions of watch hours a day of Opus audio there at least.

Nah, Dolby excels at injecting itself where not needed. Blurays support 8-channel LPCM (uncompressed) audio, yet Dolby managed to push its proprietary junk codecs in there.
