Algorytm of reducing details of map in Locus

Hi,

I am looking for an Android hardware (tablet) for Locus Map.

My main concern is to have a map zoomed out as much as possible without loosing any details from a map (i mean have visible even smallest roads/paths).
Normally (from my experience with other apps/maps) the best for that are devices with highest resolution of screen, but in Locus something works unexpected.
I have tested 5 devices lately (same version of Locus - newest , same map, defaults settings, etc)

In most cases bigger resolution of screen allows showing bigger map without loosing any details,

but I can not undestand why my phone (Samsung Galaxy A55 - 6,6" 1080 x 2340 px) shows more on screen than theoretically better devices: Tablet Huawei MediaPad M3 - 8,4" 1600x2560 px)?

How to pick most optimal device in such criteria?

Is there a way to configure the Locus Map a way to not lose details such quick?
