I am unable to reproduce this issue in 1.17.1.

Can still reproduce it in 1.17.1. End fog completely disappears at around y=319 for me.

As far as we can see, this does not affect blindness effect, was it misnamed in the report? And the end fog is linked to the Ender Dragon fight. So when you go far enough from the dragon for the fight to end you lose the fog effect.
Can you confirm these assumptions?

Yup, @timurn you're right, this doesn't apply to the blindness effect and also doesn't happens when you end the Ender Dragon fight or you go far enoguth from the Dragon. (I haven't realized this even though I played MC for more than 10 years lol)
This report should be resolved as invalid. And the real issue to fix should be MC-206610.
Thanks and sorry!
