A few years back I wondered "how much energy is wasted by the ice/water dispenser on a fridge"? I couldn't find two similar Kenmore units (one with and one without) to compare their energy ratings. Realized that Kenmore/Maytag/Whirlpool/Amana come out of the same factory, and quickly found the exact same fridge but with dispenser from another brand. To me, it wasn't worth the 10% more energy. I can pour from a pitcher.
Some choices make people happy (freedom or oppressive regime).
But pointless choices result in confusion and unhappiness, or "the paradox of choice."
Why do some manufacturers make people unhappy? Profit! "Sell the same thing to everyone at the maximum price they are willing to pay".
To avoid upsetting yourself with the UK6090, you look at the UK6300 and the price increment, and then the UK6500 and its price increment. You splurge, and forget the whole purchase incident later.
You paid more for the same screen. To prevent yourself from having bad feelings, you tell yourself the stainless steel legs (or UltraSmartWhatever) were worth it. So they even use cognitive dissonance against you!
Profit maximization is one of those unfortunate things we face.
Utility maximization is far more beneficial (to both parties, and to our planet!), but sadly due to how MBAs are trained these days, getting more and more rare.
It takes a brave person to identify those idiosyncrasies in thinking, because the giver of advice risks the "what if they're not happy? they'll blame me!" outcome. Their reputation and time, to save someone a few hundred dollars they might have happily pissed away anyway.
This is why I don't give purchasing advice, and certainly not in public venues.
I have trouble convincing my own family not to spend $16,000 on a bloody wristwatch, or that they don't need a new MacBook Air because they could just fix their old one.
It's been a lot of back-and-forth, and learning what patience, kindness, and bravery really are. Holding that line. Not being in their face, but always delivering the same consistent message, in kind and thoughtful words. Considering their point of view, really stepping into their shoes, understanding how and why they feel that way about their choice, but if the conclusion doesn't fit the facts, kindly saying, "maybe there's another way."
