I mean that line is just describing an overcast sky, it's not intrinsically "cyberpunk" or anything like that. It's also interesting that that line has a difference context now, as rather than dead channels being grey static they're often a particular piercing blue that works just as well.
Neuromancer has a lot of tropey cyberpunk settings like mega cities and orbital utopic casinos for the rich and powerful, but then you get to Count Zero and a large portion of that book is just driving through the Georgia countryside. and I think it really reflects Gibson's life growing up in the rural south; cities were these big almost mythic things to him when he was younger, and it's reflected in the writing of the Sprawl trilogy and his other works.
