Yes they look fine - centre electrode looks dry and a reasonable colour (although that can vary with fuel and octane boosters, for example) and definately not oily. Also they all look more or less the same, so cylinders are seeing the same mixture, etc. The threads look a bit oily, but that can come from other causes like leaky rocker cover gaskets.
That said you say you have white smoke, and if that's the case, you have some oil burning, but not really sufficient to show anything much on the plugs.
