Alot better then I thought they were gonna look. Lol. Very similar to what mine look like on a 150 with a 62 32. Mine are a little less rich then yours and we will go to a 30 jet next time out and take a degree away from it. My threads and base are slot cleaner then yours. I would say it is oil as well.

Are those the last plugs or did you change pressure and have another set to post? if those are the last plugs go down 2-lbs of fuel. on the next hit evey time you lean it out you need to pull a little timming once the fuel is good you might be able to creep some timming back in.
