Hi Graeme,
What I’ve read (technical papers on the color.org website) about V4 ICC profile seems to be better than the current V2 when comes time to convert in CMYK (using a CMYK V4 too).

what are your technical reasons for moving to V4 though ?

Right - since technically, V4 doesn't add a whole lot (some extra per channel
curve types, better internationalization support of meta-data) and has
some disadvantages (elimination of absolute colorimetric support for
display profiles with standard CMMs, confusion about L*a*b* encoding,
confusion about the black point), it's understandable if wider compatibility
is more important than "having the latest".
