I can say that I had very bad soot on my oil burning engine- the cool thing is that you could tell what side of the engine had the problem has one tailpipe would soot up as opposed to both (true dual exhaust setup).

No smoke.

After the engine change, the soot disappeared.

In my opinion, black soot on the tailpipes accumulating over 1k miles should be considered a warning sign of possible oil consumption. The pipes will get dirty, especially with test pipes, but just a heads up .
