Prores444 isn't lossless.
I'm not sure what makes people think that it was in the first place.
i don't think that many people think it is, but it's a *very*
good tradeoff of quality vs file size with the conveniences (and
annoyances) of a quicktime file.
and while it's not lossless, the degradation i've seen so far
are virtually invisible and nowhere near the stuff in the
current case.
but how about contacting arri directly about the artifacts?
i'd assume they'll have a clue what caused it, and if they
haven't i'm sure they'd be very interested to find out.

ps: as a side note, i did some tests recently with DNxHD185X for
a greenscreen shoot, both in hardware (blackmagic shuttle)
capture and in software conversions, and had very visible block
artifacts in both when pulling the matte and despill. ProRes422
on the other hand was very usable.
