Dark mode is one of those 'not excited that you have it, but i'll be very upset if you don't' features. On 2x products I worked on that lacked it, the demand was tremendous, placing it in the top #5 demand. By itself, you're right, it would not lead to PMF but lack of dark mode created friction that spurned users to look for other items they did not like to justify decisions on whether to stay or leave. An unusual experience.

Whenever I see "now with dark mode!" on a product I'm already using, I roll my eyes.
