After as little as six months some of the individual LEDs in the

To the extent that the lamp was failing to deliver it's effect?

These were in a run of wall washers, so the effect remains ok, but
there is growing variation in brightness now depending on how many LEDs
each lamp has lost. It was just surprising how quickly LEDs began to
fail.

There is also a concealed uplighting run of blue LED rope lights in a
raised section of ceiling (these have performed better with no dropped
LEDs yet).

so, a heat effect (the up-facing ones being able to dissipate heat
better)?
