4627 is actually manufactured in two different locations and there is a slight difference in the appearance and texture although the burn and throw are identical. I order by the pallet and request a particular lot number when I can because the only difference I can tell in a finished candle is that the more yellow, softer "vaselinish" version produces a deeper color and I like to have it for my batches of reds at this time of year. On the other hand the type you have now produces a firmer candle. If you order by the case, pay attention to the batch number and location on the box you have now. BTW the last discussion of any sort on this subject that I've seen was years ago on the old TSR so I don't think you would have ever found it in a search. Back then we chalked it up to just different batch runs on the production of the wax and it wasn't until I questioned a distributor that I was told about the difference.
