Look good SJ, you were lucky with the probe and those direct flames, they don’t mix well together, I always bring my cables out over the leg of the plate setter.
Regarding the not being coloured on top, I had similar in my early days with the Weber & only just remembered a technique to try next time.
When you put a pizza on, get some glowing red charcoal from the egg & place it on the grill next to the stone in a couple of places, get some extra heat up there. Ideally if you had the egg-spander kit, you could put the charcoal on top of the pizza on the upper grill to replicate the heat from above.
