... I think it will depend individually on the piece and the owner. If it is a variation of a model like the Dragon Automaton or Charming Bird, but with other materials and color combos, then probably yes. If however someone lets the artists micropaint his wife and daughter or his ancestor the 2nd Viscount Whatever...
then probably no.
For the entry level pieces (ok that wording's a slap in the face at >100k) there will eventually be a configurator. Don't know if public or just on request tho.
