How much would one need to increase video-bitrate (%-wise) for an increase in picture quality to be noticeable?
Assuming we're talking about a fixed resolution (say, 1920x1080), is there (in someone's experience) a minimum amount you need to increase the bitrate for the quality increase be worth the effort of doing so? 15%? 30%? 50? 66? etc.
(Obviously there's an issue of what quality is good enough for the viewer, based on screen size & viewing distance, but this is assuming you DO want to increase the bitrate)

It really depends on the previous resolution/bit-rate you are 'increasing' from.
The jump in bit-rate to handle 480i video to 720p video is jaw-dropping fantastic on a 40" or bigger screen.
The jump in bit-rate from 1080 to 4K is fractional on screen sizes less than 60 inches.
So your question is interesting as a discussion topic, but not really answerable.
