In the CRS nomenclature it's "Doctoral level university degree (Ph.D.)". My French-language ECA says "Doctorat en philosophie (Ph.D.)". Note that my PhD was in Physics; I think certain doctorates, like medical doctors only count as Master-level in CRS (135 pts, rather than 150).
I don't know about WES, I went directly with ICAS, basically because I didn't know any better when I chose to go with them, and had no idea they are sooo much slower than other companies (plus they said at the time it was only supposed to take about 20 weeks...). When I realized my mistake I had already spent considerable time, money and effort getting my original transcripts sent to them (I had UG degrees from France, where it's really unusual to have the institutions directly send documents, so I basically had to beg various people to do that for me as a special, one-time favor...).
