For me it's not that glaring.

On darker ambience dark colour schemes go easier on the eyes. I was a light-mode person until the office grew darker (because of some remodelations) and now I need dark mode to not feel the light attacking my eyes.

Also dark mode probably looks "cooler", less of an office job and more "hacking" vibes.
