More recently Philips has started selling the Dubai-style bulbs worldwide, branded as the "Ultra Efficient" range. They're expensive though, as you'd expect.
I believe BigClive did a video on those, and while they did indeed use more LEDs for improved efficiency, they also had a more complex and thus failure-prone driver than the original Dubai ones.
In other words, more efficient, but not longer lifespan.
Are you sure those are the same bulbs? The ultra efficient versions sold on Amazon have reviews going back to 2017. Supposedly the Dubai-style bulbs were only available in Dubai even a few years ago.
