TBH doesn't look very accurate when I compare it to GTA V map. Someone from the Reddit has already made a very good comparison of the map for Night City in comparison to The Witcher 3.
This may or may not be 100% accurate, but I think it's fairly close.

GTA V map also looks much more dense with more roads and buildings while being ~120sq km vs ~77 sq km.
