@YouTube Can we please get an option to block channels in the YouTube App for mobile and TV? Also a grey scale option for the YouTube logo for TV cos the screenburn on OLED TV's is becoming a bit of an issue. 
Just to confirm, are you referring to the YouTube main app or the YouTube TV app? In the meantime, we can take your feedback about a gray scale option for the YouTube logo and pass this along. You can also send it by clicking your profile photo > Send feedback. Keep us posted!
