On the PS5, we still cannot zoom into the map as far as we could like in the PS4. I can't speak to Xbox or PC, but I have read that this also persists on those platforms as this relates to how the maps are not supported on 4K resolutions.
PS5 was released in Nov 2021, and when this issue was discovered, most of us attributed it to a new platform and will be fixed eventually. Fast forward 2 years later, we still have the same issue. Hopefully this will get fixed soon.
