The Alexa voice controlled interface is available. The only thing I haven’t figured out is how to use the Firestick to change the source. (Because if I want to go back to DirectTV, I have to first use the Samsung dumb TV remote to switch back to the other port, then use the ATT DirectTV remote to navigate around the DirectTV interface.).
