Unless you make the effort to power-off all your consumer electronics the savings from just the ATV is almost certainly negligible.
I'm normally conscientious about turning things off or in this case letting them go to sleep (and my wife hates lights in the bedroom where we have one ATV). I typically measure my amps and processors for their idle or standby draw (Kill O Watt meter), but had never measured an ATV, it was easy to get to the ATV4G in the bedroom. They seem pretty efficient, when in use (watching an episode of Orville with FoxNow App), it bounced around from 1.8 to maybe 3 Watts. When in standby (power light out, wired ethernet so maybe no WiFi), it measured between 0.4 and about 2 watts (it probably dozes then checks things periodically). I imagine the ATV4K will be a little higher with the 4K upscaling, I'll measure it when I get a chance.
