Has anyone else noticed this?

A few weeks ago I started using night mode. I haven't been seriously documenting this, but it seems my laptop battery lasts longer since I did that. I'm no electronic genius, but to me it's reasonable to think less power might be being used with the dark background. Any truth to that?

'"Overall, while dark mode works only in particular settings and may be able to save some energy on certain types of displays, it is not a guarantee. It can be one of the ways to draw less power when displaying apps and websites on screens, and only in OLED and AMOLED displays. "

How can I tell if I have OLED or AMOLED display on my five year old HP laptop?

A quick search with the model number of your laptop ( on the label on underside )
will take you to an HP specs page that will tell you what they used.

Here's someone asking about theirs :
