totally[/i] dark with no dynamic lighting...
None of these sceneries have any dynamic lights, and since there's nothing in the scenery which will lit the airplane, its appearance at night will be exactly the same as any other default airport.
also take a look at the ground texture. Very low quality. Had this problem both at LAX and YVR
The texture looks exactly as it always did at night, before dynamic light was first included in the sim (so it's nothing to do with 4.4), and its resolution depends on the max texture size, which at KLAX must be 4K, otherwise you are not seeing the same resolution the scenery was designed with.
When you turn the airplane dynamic lights on, normal maps (that are normally inactive at night, until a dynamic light hits the texture), will appear, giving you the illusion on an higher resolution, and that's entirely normal as well.
