I should have clarified I'm in America and my only interaction with appliances are from the country I live in.

Generally a heat pump is more efficient and better for many applications but here in the states they're very uncommon. Basically everyone has hot and cold water connected to the clothing washer.

Dishwashers opening themselves is just a feature some of them have but it isn't necessary or really useful. I'm glad you like it but ultimately it serves no real purpose.

Induction cooktops are among the worst appliances ever invented by humanity they are truly terrible. Again I'm glad that you like what you have and that's all good for you but generally people are unhappy with induction cooktops and they are very unpopular here in the states. Also they're hell in a handbasket to work on.

In terms of efficiency your dryer is pulling the exact same amount of power it has always pulled dryers have not become significantly more efficient over time the issue is a physics one we have to remove moisture from clothing and that requires a minimum amount of energy we're never going to get around that. If you are experiencing less energy usage on your bill most likely that's a placebo effect abd your dryer has nothing to do with it.

Moreover efficiency is a double edged sword for example washers use a lot less water per load but in reality they don't they just use a small amount of water several times throughout the cycle. A washer back in the 70s had a maximum cycle of about 30 minutes that's how long it took to wash clothes because they use a tub full of water nowadays they'll use a quarter of a gallon four times throughout a load making the wash time almost 2 hours. Washers and abusing more electricity but a little bit less water which equals out to zero savings.

The price difference of energy costs per year on a refrigerator sold today versus refrigerator sold 20 years ago is like $10 not worth the savings definitely not worth the crappy technology they have put into those appliances.
