Good post! The point about the seats folding flat is a good one. However just to prevent confusion they don’t fold completely even with the rear cargo floor. However there is significantly less of a height difference between the rear folded seats and cargo floor in the GX vs LC. However what I think accomplishes this is not a different rear seat design, but rather a taller cargo floor in to order accommodate the rear 3rd row capability. This appers true of non hybrid 3rd row capable LC’s as well. I have not put a tape on it, but the wheel wells and interior accessories appear significantly closer to the floor on the GX vs the LC. However the published cargo volumes don’t seem to bear this out with the GX claiming about 2 more cubic frat of storage volume behind the 2nd row. Here are some photos first the 3 of the LC including, then the 4th is non US spec LC with 3rd row then the last two are GX both with bench and captains chairs.
