No. I doubt you got an accurate plug reading unless you got the condition for several seconds then killed the engine and immediately pulled the plug. Do you have DFCO enabled in your tune? Who tuned your ve table?

I know in the stock tune fuel is cut completely on decel when there's no throttle input to save fuel. Mine does this as well.

How do the other plugs compare? The electrode tip looks fine, and there's carbon around the tip so it doesn't look like obvious signs of a lean mixture.

The plug looks fine. Its perfectly normal as mentioned, to go lean on decel. It should actually be off the chart lean due to DFCO.

Also you need to cut the threads off the plug to see the fuel ring properly.
