Calling all Spark plug specialists

Ok guys quick question here on my spark plugs.

Car: 2.0t fsi Audi A3 143k miles on the clock.
Apr stage 2, CAI, turbo bAck exhaust, stock k03, red coil pack

These are ngk iridiums one heat cooler installed at 108k miles.

Car never had a misfire until last week after I brought the car for a carbon cleaning, now it has misfiring on cold start and for a few minutes, it does not trigger cel, just soft code p031

I replaced the plugs thinking that was the problem, but still getting the misfires.

Can anyone tell me what they think of the conditions of these sparks based on 35k miles (give or take) on a stage 2 map?

This is cylinder 1 - 4 (RIGHT FROM LEFT - sorry only though about it after I took)

Cylinder 3 (middle) compared to 4 (left) and 2 (right)

Close up of 3.

Does this sparks look bad? Cylinder 3 had this oil residue on the thread plus some deposits on the electrode, and all of them had this black soot on the socket (outside of the thread) but I am inclined to believe that’s from the dielectric grease applied to the packs when installed.

Should I be looking into an engine problem here guys? Any advice is appreciated.

Thank you.
