Plains of Eidolon Captura depth of field issue

[elaine]

So as you can see, the one tree on the left in the 4th picture looks really good when blurred. But now take a look at the trees on the right (all pictures, 1st picture is zoomed). The quality is pretty S#&$ty. I tried to change some graphic settings but nothing helped with that. Kind of ruins the captura. Also if you look at the zoomed picture closely you can see that there is a line between the "good blurr" (beneath the line) and the "bad blur" (above the line). That line is marked with a red yellow. 
Trees in the far background look good but when youre a bit closer they kinda look like theyre painted with watercolors.
Since I'm a big fan of Captura and especially the PoE scene,  it'd be great if this got fixed somehow.
