Neither mean perfect surface; UPOCC stands for Ultra-Pure Ohno Continuous Cast and PCOCC is Pure Copper Ohno Continuous Cast. The difference being the UPOCC is 'supposed' to be of a higher purity the PCOCC. That of course is debatable especially once it gets to its finally resting place.

Bill Lowe says that his raw wire is polished prior to dielectric being applied so that his conductor has a 'perfect surface'. Whether that is true or not I don't know but until a year or so ago when USB microscopes became easily obtained there was no way for a person to easily verify that.

The wire in the pictures certainly looks 100% mark free to the naked eye but under the scope it appears to have a slight groove in it from the drawing process. Looking at the orientation of the marks on the wire, especially around the groove, the bottom of the picture would have been the leading edge of the last way the wire was pulled through the dies.

(and yes I run the return in the opposite direction)
