Or, App has been updated to make use of the Red path like the Walkman App and UAPP ?
Or, it's showing wrong even though with Sony set to "Hi-Res Streaming off" Amazon should only see the DAC as 48Hz capable if using Blue Android Audio route?

It should be easy enough to check the logcat and verify. I'll try to do that later today or tomorrow and report back.

Thanks. Maybe because app originally saw it as 24/192 it remembers that even if reset back to 24/48? In reality, if the offline file is 24/192 Android will downscale to 24/48 if Hi-Res off.

Because back then Sony US/EU used to care about promotion of high end audio gear, but now they switched to TWS and wireless headphones as their bread and butter of audio sales, quite understandable. I got my review sample of WM1ZM2 from Sony US by request of Sony Japan so I can start featuring it in my reviews as part of comparison with other daps and pair up with other iems. And I have been doing that for the last 3+ months, featuring it in all of my reviews on top of answering dozens of questions every week. Still need to write a full review, and the only reason I set it aside because 1ZM2 wasn't even available for sale in US (and still isn't?) so I shifted my focus on other reviews in queue.

Thanks for the explanation. Now it makes sense...their shift in commercial policies explains the scarcity of units available for review. It's a pity, because in a way is a self-reinforcing dynamic: less reviews and promotion, less sales, which in turn leads to even fewer efforts to promote the devices.

What is the model number for this? I assume this works with the OG 1A/1Z as well? Would be useful when attached to the TAZ.

Yep its great for when the walkman is out of reach or I am too lazy to stretch, sometimes its sooo far. Its a very petit little thing, disappears down the back of the couch quite often.
