APK ARM64 versus ARMABI

Does anyone know the difference between the APK's for DirecTV Stream (ARM64 versus ARMABI)? I can't get any of the ARM64's working. I keep receiving either a black screen or unsupported ABI error on a Chromecast w/ Google TV.

I did get the ABI version working once, but the navigation to log in was a bit off and not easy to use. Seemed web like, not app.

Anyone know the differences? or have a version they found to work on the Chromecast w/ Google TV?
