Well No, But in the real world the landing Lights are Off when Taxi to Ramp
Which is why my first image, that show the marshaller clearly visible, was with all light entirely off. Your last screenshot indicates the problem doesn't have anything to do with low visibility at night: it seems, instead, the marshaller is partially inside a building.
As explained other times on the forum, and of course on the manual too, GSX doesn't have any knowledge of the outside world, except the AFCAD, it doesn't know anything about scenery structures.
Which is why, there's a parking customization option in GSX, that allows to fix such cases, you want to have a look at the Maximum Marshaller distance, discussed in the GSX manual at Page 23.
