And that leads to the question, what about burn-in on a plasma screen TV?

I suspect that watching a lot of 4x3 source in its native aspect ratio
would be a problem for a plasma TV, no?

It can be, but usually the plasma will use a tested neutral gray for the
side bars, to try to minimize that problem. As far as I have read, it's not
any worse an issue than the usual burn-in problems with plasmas (and yes,
plasmas are not nearly as bad about burn-in as they used to be...but it
still happens).
