Netflix, Subtitle, Colour WASHED

Hello,

Please help, steps to follow:

Open Netflix, Press More - Account, Subtitle Appearance - Change ( Font to BLOCK , Colour to YELLOW/GREEN/BLUE ) ( Shadow to UNIFORM, BLACK ).

The subtitle becomes unreadable, FADED, WASHED, GLOSSY. 

Thank you for your time and effort put into reading and understanding the issue.

Thank you for any Suggestions or Possible Fix.

IS my unit Faulty ?  IS Netflix pixel colour wrong ?   Can anyone confirm the issue ?

Kind Regards,

Andy.
