Plug looks fine. But the threads would indicate that you probably have a valve cover gasket leaking oil down on the plug...
Yes! But not anymore. I got rid of the parts store chrome valve covers and installed original style orange stamped steel covers with cork gaskets. Much better now.

That tan line on the strap makes the turn nicley and appears to be near the base which is good. How does it look down inside around the electrode insulation

plug looks normal.
Clean spark plug hole, anti-seize the treads, check for leaks.
The oil burning telltale would've been in the 'socket' area of the plug....there's no carbon in there....this would not have been burnt off by the plug firing nor the explosions, it's in the cooler condensing valley of the electrode.

Awesome. Thanks.
How to clean the threads w/o dropping crud into the cylinder? Use a tap?

If it was me....
Screw in clean plug about 3 turns.
Blow out spark plug hole with high pressure compressed air.
Remove plug
Clean with lacquer thinner on clean rag buy twisting the rag and dragging junk out of the hole.
I use nickel anti-sneeze in the plug holes.
BTW, one big mistake I have seen is OVER 'sneezing' the plug threads....reminding you that some of the threads protrude into the combustion chamber....anti- sneeze is conductive...I've seen guys 'kill' the sparkplug by over sneezing.
