This was probably first requested the first time an app was downloaded from the store, and many times since.
It's possible to get the info but it's a whole lot of work, where you can set up a service and use something like onAppInstall() to send the data to that server, and if you do so, make sure you take GDPR into consideration.
You can get a bit of an idea of what devices are popular with your app based on what devices people note in their "contact developer" messages.
