while browsing on something totally unrelated to Netflix, I found the following page which might be helpful to those having issues with Netflix in any way, be it content or accessibility.
Their page states that they want to help make Netflix accessible to any type of disability.
The accessible Netflix project | Advocates taking steps to ensure Netflix accessibility for everyone
You can contact them via a feedback form, or use the
firstname.lastname@example.org e-mail address.
Netflix isn't as popular here in Germany yet, but maybe that'll help someone having accessibility issues.
