Looks like Kimera can't set the shade mode properly (Modified version is flat shaded, original is smooth)
Very technical information follows;
After the polygon data in the .p file follows a section of 100-byte sized chunks, at offsets 8 and 12 you have two dwords that enable/disable all sorts of effects, among those smooth shading. If this information is missing or zero it will (apparently) revert to flat shading.
If Borde is still around I could help him implement some of these effects in Kimera
