Thank you.
is the App screenshot below the correct App for Shield to support bit perfect playback.

My pleasure. Yes, that is
USB Audio Player Pro. It's the one you want. It'll cost, I believe, four or five dollars.
Actually, what I think you will need to do is
first buy and download the app, which is version 5.9.9.9, but when you side-load it into your Shield (which you can do in a fairly hassle-free way -- unlike some other side-load methods -- with "
Mibox APK Installer for Android TV," which will also cost a few dollars), UAPP will give you a message that says
"License check has failed." And it won't open. (This is what happened to me.)
What you do
then is write the developer at
support@extreamsd.com, tell him this, and he'll send you a beta version 6.0.0.8 or -9 or whatever it's up to now. Install that, and it will work.
Beware that the beta will only work for one week. When it stops working, just write the the dev again and he'll send you an updated version that will work for another week.
He will tell you that there's a way you can just increase the version number of the apk you have, but right now I forget the details of exactly when, where and how you do the increase-number thing so that it will work.
Also know that although UAPP will indeed provide you with bit-perfect sound, it isn't fully supported for Android TV, which means it's operation is a tad wonky. For example, I've found that in a list, say, of albums, the album you've selected is not highlighted, so you can't tell where you are in the list. And some other things like that. You have to move around a bit more than usual to know where you are in the app.
UAPP is apparently is made by one guy, and he told me it would take him several extra months to provide support for Android TV, implying that this was not something that's on his to-do list.
For bit-perfect audio on the Shield, you can also try using the
Sony Music Center app, also
JRiver, both of which will also have to be side-loaded.
When you side-load an app, it doesn't show up in the regular app list. You need to get the app "
Sideload Launcher" and all your side-loaded apps will show there (along with some non-side-loaded apps.)
Good luck!
