Honest question: how well-lit is the area you use your computer in, and have you tried turning down your monitor's brightness? I'm as baffled by the popularity of dark themes as you are with light themes, but I'm sitting in a fairly bright room with natural light and a monitor at 35% brightness. In these conditions dark-on-light and light-on-dark text are equally pleasant to read, and I opt for light themes when given the choice simply for consistency. If you're using dark themes because you browse the web in the dark, it seems to me like changing your conditions is a better solution for your eye health.
It really bugs me for my monitor to not be at or near max brightness because of how terrible the colors look at low brightness, even on high end IPS panels. This isn’t an issue on my OLED phone, which has great colors even at the lowest brightness, but nobody makes 27” OLED monitors and if they did they’d be prohibitively expensive.
Display brightness establishes the absolute limits of its output color space (i.e. the display's dynamic range).
By which I mean: bright colors won't be anywhere as bright with a dim display as they would be when the brightness is turned up. And the difference between dark and light colors is more pronounced with a higher brightness level.
I use Redshift continuously day & night and at first it looked really weird with the red tint, but after awhile my brain got used to it and now I don't notice at all (and it is a lot more comfortable), looking at other peoples' screens looks blindingly bright; makes me feel like a vampire...
Man I would pay a lot for 15-17" MacBook (or properly supported Linux machine) with proper OLED screen (from what I read the already discontinued Lenovo's suck at direct sun).
As I understand it, OLED burn-in is a _mitigated_ problem but not a _solved_ problem, and I wouldn't expect to see OLED monitors so long as that state of affair continues.

Not all content is too bright and white. Videos for example playing at full screen, I would not want reduced brightness for. It's the bright 100% white background of websites on a large monitor that is not comfortable.
Also most monitors have annoying UX for adjusting brightness, requiring two presses of tiny unmarked buttons to get to menu then change brightness.
I was very pleased when Youtube added their nightmode feature, which I leave on always.
