Comment:

 In the interest of clarity, I am going to close this ticket and break down
 issues on a particular case by case basis.

 The case by cases thus far registered are:

 '''SWSCALE: Incorrect Values in Full Range Conversion RGB to YCbCr'''
 https://trac.ffmpeg.org/ticket/3801

 '''SWSCALE: Quantization Errors in Y Studio Range'''
 https://trac.ffmpeg.org/ticket/3794

 The spreadsheets  here are still useful for anyone looking to test
 theoretical values.
