We believe it is, and although the fuselage diameter stays the same, the internal dimension is being increased by about 8" by the use of thinner insulation material for cabin walls.
Given the regular statements that airlines have no concern for any feature that increases passenger seat comfort, the only reason for this can be to insert another seat. The 787 was not announced as changing from 8 across to 9 across until the point it entered service.
The 777 is already one of the noisiest aircraft around inside the cabin, and the thinner insulation can do nothing to improve that - in fact presumably the converse.
