I just tested a buffed Veritas PM-V11 chisel. Honed on a Shopton Pro 1000, then buffed. As expected, it passed with flying colors. Buffing took longer than for the Buck Bros chisel, which is not surprising.

Photos below are after chopping off 20 pieces of the maple test piece. I stopped taking edge-on photos because it takes a lot of time to set up each one, and I don't think they were providing much more information than the bevel and back photos.

At the end, it seems subjectively slightly sharper than the buffed Buck Bros chisel -- it feels sharper and can shave hair a bit more easily. But those differences are trivial compared to difference between buffed vs. unbuffed.
