I had to add "-vf colormatrix=bt601:bt709" to ffmpeg so the RGB -> YUV color conversion will be correct.
Now it looks and measures 1:1 to the RGB.
EDIT Important!
The "-vf colormatrix=bt601:bt709" should be changed to "-vf scale=out_color_matrix=bt709" because the colormatrix command is only 8bit and it dithers down to 8bit.
While the scale=out_color_matrix=bt709 command bypasses any conversion while retains correct chroma values between RGB to YUV conversion.
