Hmm... I think a more accurate statement would be 'we have Venus
mapped to a greater accuracy than any unclassified map of the seabed'.

That being said; AFAIK there are lots of areas that *are* mapped to a
high level of detail, but the basic problem of getting even 1m
resolution across the entire ocean bottom is staggering.
