William, thanks for the interest in the feature! 1. What platform are you using? 2. Did you try enabling dark mode in the OS settings?
I have recently merged the change to make the feature available as a part of Experimental Web Platform features flag (chrome://flags/#enable-experimental-web-platform-features). Feel free to check it out in Chrome Canary.
