My interpretation of this update is that the plane will be more visible once the black dot has gone. See, the black dot is some sort of assistant sprite - it's
not a LODed model. When the dot disappears and you can no longer see the plane, that is when it's switched from assistant to LOD model.
My guess would be that they have simply made the LOD models darker the further away they are. But that is just a guess.
Also, I would be hugely surprised if this fix applies to only SDTVs. It is to help SDTVs but I can't see it only applying to them.
Guess we'll have to wait and see
