Are you actually asking a question?  I can't follow what is supposed to
be going on here.  No quoting and top posting makes this unintelligible.

YUV<->RGB conversions are not lossless.

Subsampling is not lossless.

x264's lossless mode can only store the information it is given.

If you want to store RGB video losslessly using x264 through ffmpeg you
will have to use the codec libx264rgb.

Trying to control what swscale does is a lost cause.  Perhaps that has
been improved since what I learned ~5 years ago and you can actually
control colour range and colour matrix.

Anything else?
