I think TV static is like floppy icons in UIs. It's been referenced enough as a no-signal indicator, as well as a deeply rooted cultural thing, that even Gen Z will recognize it.
It's funny because they'll recognize it as a cultural artifact. Used for artistic effect. Whereas, for me, it meant something more practical. Meant I was up too early or too late for anything to be on the telly. Or it meant something was wrong with the reception and I'd have rearrange the rabbit ears. Later on, it meant my Atari 800's connector had gotten loose and I'd have to go back behind the massive TV to tighten it up.
I see a lot of bill boards showing "No Input" and "HDMI 1" on a pastel blue starry skyfield. It's what pops up when you google image search for "no signal samsung".
