Did early consoles include screen savers / color-cycling?

[Kid Ice]

Screensavers are actually BAD if you use a lcd panel. Leaving the screen turned-on slowly-but-surely wears around the fluorescent bulb inside the screen & leads to premature dimming of the display. With an LCD, it's better to turn it off. "I know the Atari VCS/2600..... Did any of the earlier consoles [than the Atari] include color-cyling?"

It's called context.
Not that it matters
but it is what I meant. I was thinking of console pre-1977.

Say, wasn't Veronica Mars cancelled?
