A poor match will be inclined to generate TVI...

Could somebody please explain why feedline SWR should produce any more
general TVI in the neighborhood than if the match is perfect?

If the match is perfect, the antenna radiates all the power from the tx
(less line loss). If anything else radiates part of that tx power (the
feedline, you say), the total radiated power still can be no more than when
the antenna radiates all of it. So if tx harmonic levels are the same in
both cases, why should "feedline radiation" have much affect on TV receivers
in the neighborhood?

Are you talking about some very localized effects (tx feedline running next
to your own TV set or TV antenna, etc)?
