This was a validating read. I used a Samsung G9 OLED for the better part of a year and eventually had to stop because the eye strain was terrible. I found myself avoiding my desk because it was a chore to look at the display.
I've moved back to using a pair of 4K LCDs that I had, and honestly the resolution and aspect ratio are better for text and programming anyhow.
LCD is just the better technology. Besides what this article is about, OLED have awful burning and longevity problems. They're great for watching movies on the first month (and that's what gets them sold), but really not much else.
