Quick plug check: Normal wear or High Speed Glazing?

I thought I would check a plug while I was under the hood removing A/C system. I compared it to the Haynes manual and to me it looks like a hint of high speed glazing. I took some good close up pics for opinions. They are Bosch Platinums (dropping them when I do the blower, so no worries) if that matters.

Thanks.

They look pretty normal to me. In fact unless those pictures aren't a good representation (which you clearly said they ARE,) I don't see any glazing, shiny spots, etc.

You could go one heatrange colder if you're truly worried, but I don't see anything odd enough to warrant doing that.
 
Pictures are representative. There is just some yellowing, seen on the first photo with the electrode to the right side. Not much, but a little. That is the only thing that made me question if it was high speed glazing.

Not too worried, as I said I will be doing a range colder anyway with the blower install. Just wanted to see if this was a sign of any problems I should look into prior to the blower install.
