I think Lower Decks would be difficult to not get a 100%. 4 of 8 starring cast members are women.

The article linked shows voyager pretty high, but DS9 surprisingly low for how many women are part of the show.

I’d be curious to see how the newer shows stack up. I’d bet they’d do a bit better, but it’s hard to know. For example, Discovery has Burnham and Tilly, and they even share quarters so they are likely to talk a lot, but it is still a pretty male dominated cast. Lower Decks on the other hand, I’d be surprised if it didn’t get a 100% since half of the starring characters are women (Mariner, Tendi, Freeman, T’Ana).

Traditional LCD screens actually use more power to make black.

OLED screens might save a tiny bit of power though.
