The font itself is not enough for good readability.
So-called "UI/UX" designer are making a lot of fancy work to make things illegible. Contrast between background (aka "paper") and foreground (aka "ink") is going down and down. So, no matter the font of choice, text is becoming less readable (and less relevant) also because of color choices.
While video and audio contents is getting more and more attention.
Too much contrast is hard to read, though it also depends on the quality of your monitor and the ambient lighting. OLEDs have infinite contrast ratios with black text or backgrounds, which is too much.
For example when I first saw this new CV I thought, "that's really easy on the eyes".
Generally OLEDs don't use off for black outside of special-effect low power modes. The display only has stable contrast above some threshold brightness that in a dark viewing environment is going to be noticeably brighter than off, and it looks awful below that. The #000 point is set well brighter than that level.
I don't agree it noticable. My OLED screens all look the same as off when all black in dark rooms. And if you look at specs and display reviews they typically report contrast ratios of 1M:1.
There’s a trick I picked up on one project and made lots of use of in the one I mentioned elsewhere in this thread. Everyone at that time was using charcoal black (#333) text on light grey backgrounds (#e0e0e0 or #ddd) or even middle grey backgrounds (#ccc), or white text on dark grey or highly saturated backgrounds and it was a mess.
You add a 1 pixel radius, zero offset 70% opacity white shadow to dark text, or the same shadow in black to inverse (light) text, and the letters pop without the shadow being noticeable except under zoom. The page takes a little bit longer to render, but at least you can read it despite the designer’s attempt to sabotage basic UX principles.
The translucency makes it work on other colors as well, if you have color coded labels for instance, like a dark blue bar with grey text.
Contrast is not the end-all-be-all I have pretty severe astigmatism, and when contrast is too high I get quite severe visual artifacts. For me text is more legible if the contrast is a bit tamed.
