I don’t even have an OLED display for my desktop and I’ve still preferred pure black background for the longest time.
I’m glad dark mode is a standard unlike 10+ years ago when you had to hack it in yourself most of the time. But Ui designers just seemed to be afraid of trying anything outside the standards Google/Apple etc put in place.
We need more glossy dark mode themes!
I had a similar blue & black theme through Windowblinds back on Win7 for a while.
