The fact it has a proper dark mode that doesn't require sites to support it is one of it's best features IMO. It is a lifesaver when trying to get a small child to sleep.
I, too, like dark mode. But, I've found several instances that required the site to make modifications to support dark mode. Most recent example was a QR code rendered as <svg> with a transparent background. The parent container had a white background. Samsung made the parent background black but didn't invert the QR code color. So as a result the QR code was unusable.
