Tried a lot of settings, but with enabled network I never got the standby power consumption down. It should also be expected that the TV uses the advertised amount of energy in standby mode with the default settings, which was really not the case for me.
And don’t get me started on this „might increase power consumption“ message. This might actually not be Sony‘s fault, but the EU‘s, but it really gets annoying when it pops up all the time.
For me (KD-55X9000H) the default settings give low power consumption. Enabling WiFi does not make a difference. Enabling HomeKit Wakeup (not Airplay, as I mentioned before) gives a huge power usage. Disabling it again doesn't bring it down. Only after a factory reset I got it down again. Took me a while to figure this out. Also, it might depend on your firmware version.
