Foliage LOD or something else?

Hi good people,
Probably a total newbie question, but can’t solve this riddle myself… I’m trying to browse the internet since yesterday but no solution was found…
Basically, for some still shots, I need to use high-quality trees and it covers equate huge area, so I’m using the Foliage tool to populate trees. The problem is that even if I turned off all LOD for static mesh trees I’m using, when I’m zooming out the Foliage trees looks faded as LOD is applied or something.
1st image - a closer look, all trees remain the same:

2nd image - zooming out and see trees on the left faded compared to the trees on the right which are static meshes:

Can anyone advise on this and maybe navigate to some workaround? I assume something to do with shadows but I tried to play with that and have no clue… BTW, Raytracing is on.
Many thanks!

Do you have distance fields on?
