A less wordy answer -
Notice at the very tip (which I didn't buff heavily with the yellowcake, but I have other pictures where I did - you can see light scratches), there's really no distortion other than oil.
I think most of the finer full polish bars would look like the linde bar, or they wouldn't make a bright polish on a buffed surface (stray scratches would leave spider webbing).
Makes some sense given that the yellow bar is sold as a cut/color bar and not just a final polishing bar. I don't have enough clean wheels to do a huge array of finishes from different buffing bars, but a decent guess can be gotten by using them on soft wood.
The big benefit isn't so much the fineness of the yellowcake, it's "fine enough", but on the buffer, it still eliminates the wire edge and doesn't draw out another significant one.
