Just incredibly sad.
We should be punishing product manufacturers whose products fall in the bottom quartile of life expectancy - returns by Freepost (receiver pays the postage) and get £10 compensation + money back or replacement.
Perhaps then we could start addressing some of the planned obsolescence in low value goods.
To answer your question, it really depends. If they run cool, are a good design, and aren't defective, they will last incredibly long. Often, one or more of those things isn't true.
Customer must just be easily able to tell apart better LEDs and they can just by looking how many LED filaments per watt they contain.
I think China can make plenty of those if they become fashionable.
I would still gladly buy it if I was sure that higher prices actually pay for more undervolted LEDs and is not a marketing gimmick to "instill sense of quality".
When I make buying decisions, I often struggle with exactly that: I have no way of telling what is "good" or "bad" quality, and I have to much experience with expensive stuff being repackaged cheap crap, so I end up buying cheap crap more often than I should.
One thing I really hate are discounts.
brand: this product is worth X brand, during some random days in the year: GUESS WHAT IT'S JUST X/2 TODAY YOLO me, always: you are ripping me off during the rest of the year
IMO, interior designers and light manufacturers need to work together to make attractive energy-efficient lighting solutions. For example, recessed halogen-based spotlights are a nightmare for LEDs - there's nowhere for the heat to go. Even if you get an LED bulb from aliexpress, it won't last long because of the lack of proper heatsinking. Meanwhile there's plenty of surface area that could be utilized for heatsinking if the fixture is designed for LEDs from the ground up.
I've been using LED lighting at home for a decade+ now. Some bulbs I bought back then still work. Many of the newer ones are failing fast, obviously struggling with heat in the fixtures they're in, which has been bothering me. The bits I like best are adhesive LED strips driven by a stand alone power supply with PWM dimmer in the living room. They're mounted in aluminum backed diffuser rails. I expect that stuff will last near as long as I do. They're under-driven and run cool, and the power supply seems high quality.
That's the eternal question: How many computer scientists does it take to change a lightbulb?

What would be interesting to me is how reliable the stated 1 Watt of those Phillips E14 Candlelights are, mine from Osram are rated at 2,5Watts. Otherwise looking very similar in specifications.
> The Phoebus cartel existed to control the manufacture and sale of incandescent light bulbs. They appropriated market territories and fixed the useful life of such bulbs. … The cartel tested their bulbs and fined manufacturers for bulbs that lasted more than 1,000 hours.
