Yes

The "true black" OLED displays have their part of the display off where there are black pixels, if I am not wrong. So, wouldn't dark mode suit well for those types of displays?

GP is arguing that exactly because there is no backlight, the contrast between on/off is uncomfortably high on modern screens compared to the CRTs where Windows 2/3 was running.

I agree. Most websites with a dark color scheme use a dark grey background and even off-white text.

OLEDs are per-pixel backlighting, so they can go full black on a single pixel.
