If this is the case, in the same way old maps were somewhat incorrect, could that be the same for ours now?

To some extent, yes. Unless I'm totally mistalen the distances of some stellar objects are very accurately known but some are fairly rough estimates. So the overall shape is probably very well fixed by the most accurate bits but the details are a bit fuzzy.
