I also have (partially outdated) custom stylesheet that fixes that for websites I {used to,} visit often: https://jenda.hrach.eu/w/blackweb

no idea to what extent, if at all, it is true. I can imagine there being a grain of truth in there but that implementing this correctly is much more difficult and nuanced than it might seem at first glance - most "digital designers"[1] probably don't get the budget/freedom to properly tackle accessibility in their commercial projects, I can also imagine that the majority of digital designers are 'young' and have close to 20/20 vision making it that much harder for them to truly put themselves in the shoes (eyes?) of people with lesser than perfect vision[2].
as someone with only a laymans' understanding of all this stuff I'm probably guilty of talking out of my **; I welcome someone with real graphic design credentials putting me straight :D
[1] "digital designer", a person working in/with visual design, who started employment, or was born, after the release of the first iPhone ;-) (alternatively someone working in the design industry who never had the privilege of buying a copy of "The Face" for the simple fact they we not born in 1985)
[2] a category I begrudgingly have to admit to being part of more and more ;-/
