For TVs the jumps between grades isn't that big TBH, like maybe on the order of 10-15w per grade. You can get a feel for it by searching for TVs on one of the European amazon sites and clicking on the product fiche link for each one.
My living room TV consumes 70w (as measured by me), which is not the best, but considering how often it's actually turned on it doesn't make enough of a difference. 10w of power draw equates to 3.5kwh per year if the TV is only on for an average of an hour per day, which would cost me a little over 1 euro. The reason why I replaced the bedroom TV was because it didn't have a shutoff timer, so it would stay on for days if I didn't notice, drawing 37w the whole time (325kwh, or 115 euros per year if it stayed on the whole year).
The biggest ticket items for energy efficient replacement are any appliances that stay on long term (fridge), your oven if you use it a lot (get an air fryer or a combined microwave/grill), any computers that stay on all day, and anything with bad standby consumption (get an energy meter like this one: https://www.amazon.de/gp/product/B00MHNGWDM).
Also, if you need additional electrical heating in the winter, an oil heater is the most efficient. DeLonghi makes the best ones, for example https://www.amazon.de/-/en/DeLonghi-TRRS0920-electric-radiat...
And never underestimate the savings from good insulation!
