Bssed on WebAIM Million report, it could be said that it has improved marginally (https://webaim.org/projects/million/). Yes, maybe the tools that people use are getting better, but the native experience is not getting better a lot.
From the report the biggest accessibility pitfall is still poor contrast. It's sad that user would need tools to access information that only has poor contrast.
"Oh my god! It's a giant rock!"
"Oh my god! Another giant rock!"
