The difference is sizable, is there anyway you can measure the
temperature just under the dome?

Is the fan setting the same in both cases? If so it does look like the
heat being radiated by the dome is the difference between the gas
temperatures. As I said before the bare thermocouple will be under
reading compared with one in a tube as Alex suggested.
