Well, guess I'll be the other guy.

You're objectively wrong here. While I don't doubt your personal experience, street lights like this do exist and are even pretty commonplace. Sodium lamps are still in use the world over, particularly rural areas because of the relative costs involved (They're either cheaper to produce or cheaper to run, don't remember. Maybe both). It's the sodium that gives them that soft orange light, and a quick google search will give you plenty of like examples to the above.

At any rate, the artistic decision making on display here would be legitimate whether the lamps had real world analogues or not. The juxtaposition of natural snowfall and artificially monochromatic warm light creates a unique and evocative scene.

I lived in a place in eastern Pennsylvania that had high pressure sodium lamps in exactly that color

I’ve definitely seen streetlights like this

I don't know where you live but up until a few years ago, every single lamp in my city had exactly this color, because they were sodium-vapor lamps. They've been replacing them with LED lights but still plenty of sodium lamps remain. If you do an image search, you'll find plenty of photos that look almost identical to the pixelart.
