Only within pretty narrow limits.
Classic JPEG will never be as efficient given its age, in the same way that LAME is doing incredible things for MP3 quality, but any mediocre AAC encoder still blows it out of the water.
This is in addition to the things you've already mentioned (HDR) and other new features (support for lossless coding).
And I'd find their sentiment much easier to believe if Google/Chrome weren't hell-bent on making WebP (or more recently AVIF) a thing themselves! That's two formats essentially nobody outside of Google has ever asked for, yet they're part of Chrome and Android.
