Here's a paper on the possible variations. In any mpeg-2 source, I would expect to see the slight (one sample) luma delay shown (MPEG-2 4:2:0 sampling, far right at top of p.2), not a luma lead.

Not in the source. I was talking about in propagation through injection points the TVs amplification stages.
