Though, the 27mm Panoptic has a field stop of 30.5mm, so it is larger than any 1.25" eyepiece. Hence, it would yield a larger true field.
Your comment regarding performance is true--that has little to do with barrel size and is related to design.
True field, however, can be related to barrel size, and, generally, 2" eyepieces do have larger field stops and, thus, larger true fields.
