I wouldn't say that. At the native resolution, the Librem5's DPI is only slightly higher than that of the N900, but scaled by factor 2 it is much lower:
Code:
N900 (3.5" 800x480): 266.56 PPI
Librem5 native (5.7" 1440x720): 282.45 PPI
Librem5 scaled (5.7" 720x360): 141.23 PPI
(source: https://www.sven.de/dpi/)

The UI of the Librem5 (native) would have to be scaled up by pretty exactly x1.06 to get to the N900's DPI.
My hope would be, that they just use Gnome's inbuilt scaling option, which iirc is supposed to work at x0.1 steps. That way the user could individually adjust the scaling factor.

The worst case would be for them to hard(ware) wire the scaling, e.g by some firmware or preprocessor chip, which would make it impossible for even 3rd party OSes (e.g. Debian) to change the scaling. But I don't believe that will be the case.
