No worries! It's not really a big deal what you call them in most situations, so it's all good.
I'd probably stick to just variegated to describe them since DWS (stands for dominant white spotting) in most lines have megacolon (basically, they don't digest right and the abdomen swells until they're super bloated and die, generally by a few weeks old as they start eating solids) and tends to have much less coloring on the head than yours. Depending who is talking, some people get unnecessarily bent out of shape about DWS. (Sometimes on the same level as people talking about spider BP wobble)
I've got a line where the great great grandparent was a DWS from a line that hadn't even shown megacolon (it's a gene that is commonly linked with the visual trait, so most lines carry the hidden gene that causes the medical issue. Some lines do not, but the only way to know is to breed it and see if any have it) and while nothing popped up in looking like DWS for my mentor, I've gotten a few now, none with megacolon.
Pics for reference sake. A few variegated I bred earlier
And one of mine that came out with the DWS appearance (I think there is a lower white version, but I dont know how to ID that one, this is the "classic" appearance)
