My Samsung smart TV with WiFi is specified as using < 0.7 W in standby.

Is that with WiFi enabled though (so you can turn on the TV via your phone, for example).

That is one heck of a lot. Our 2021 model Sony uses 2.0W in what they call "network standby" whether Wireless or Ethernet. I have no need for those functions so it goes into normal standby less than 0.5W measured. Annoyingly it doesnt have a real off switch, the switch just puts it into standby.

Are you sure you don't have something set wrong? Ours initally used 11W, but going through the settings sorted that out.

An xBox Series or One console will use around 15w constantly when Sleep Mode and 0.4-0.5w when off, but not unplugged. A modern smart TV which is connected via WiFi will use 15-30w when off but in standby, if it is connected via ethernet that will be around 10w lower. Turning a TV off at the wall/unplugging it is not great for it, they are not build around that. If it is an OLED then turning it off at the wall/unplugging it will harm it's colour balance and shorten it's lifespan. At most they should have reduced your usage by 1.3kWh per day, though likely less than 1kWh. 

Ecodesign requirements are that devices manufactured since 2019 must consume no more than 2-8W in network connected standby. https://commission.europa.eu/energy-climate-change-environment/standards-tools-and-labels/products-labelling-rules-and-requirements/energy-label-and-ecodesign/energy-efficient-products/mode-standby-and-networked-standby-devices_en.

I've always turned everything in the house off when we go to bed.  All those things on and using a watt or two add up, and there's no good reason for them to be on when we're not using them.  The TV and Freesat box get turned off with a free widget that came from E-On years ago.  It detects the on and off signal from the remote and physically disconnects the power to both when it detects an off signal.  No downsides at all in the years we've been using it, other than the need to press the on button on the TV to get it to turn on again.  This is a small price to pay as the Freesat box seems to run very warm all the time it's powered on.

Do you have to manually tune it (the freesat) if there have been channel changes and does it have an updated EPG when switched on? Just wondering really

Never needed to touch it since it was first installed, TBH.  It took around five minutes to set itself up when we first got it, finding channels and putting them in order, but since then it's never hiccuped as far as I'm aware.

WiFi is there to support streaming and software updates, neither of which require it to be enabled permanently in standby.
To me anything that requires that much power would have to be pretty special to justify the cost of the wasted energy, which might be more than the cost of the TV in the long term.

Our LG TV is connected to wifi again by the time it turns back on from standby, but it uses so little power in standby the energy monitor doesn't register it.  If accurate (and I have seen it register the minimum) that means it's below 0.1W.
