The bulbs not being suited to certain uses doesn't make them bad bulbs, it makes them more limited. There are bulbs that are good for external use and ones that are not; but that doesn't make the external ones "better", it makes them different. There's tradeoffs. And the tradeoffs for LEDs have gotten better over time, but are still there.

You don't go buy offroad vehicle, then complain it doesn't drive as comfortably on the highway and say it's an objectively worse vehicle. It was designed for a different goal than the 4 door sedan you're comparing it to. It does better at that goal, and worse at others. And, over time, offroad vehicles have gotten better on highways; they'll just never be as good.
