That's your opinion. And since you claim to have 19 years of experience as an audio engineer, I won't dismiss that out of hand But until Apple makes a hi res audio compatible HomePod, there's no way to do a comparison.
I hope you'd agree that the technology exists to stream hi res audio. KEF and Bluesound speakers have been doing that for years. So the only reason why you can't do that with the new HomePod speakers is because of product design decisions made by Apple. Personally, I believe that if you're going to offer hi res audio through Apple Music, that you should design products that complement that feature. But so far, Apple has refused to do this. So if you want to listen to hi res audio, you can't do it with any Apple headphones or speakers.
