You're confusing 127 with 110. VERY different things. 127 is basically roll film like 120 only slightly smaller, about 4 cm across, thus the 4x4cm "baby" Rolleis. Far larger negatives than 35mm and capable of fine results with modern films if the camera is. 110 is a sub-miniature format with the sizes you list.
You are right, I wrote 127 and I meant 110. I was surprises those new 110 rolls were pre-flashed with frame boundaries. I actually would be surprised just the same for any format.
