Installed DynDOLOD, DynDOLOD Resources, EVT (custom large), EVT billboards (custom large) from scratch. Medium preset selected while generating LODs. Perfect Whiterun's pine tree LODs still don't match the rest of the pine tree LODs generated using EVT's billboards.

Sorry, had to upload it to Mega.nz because the text file was too big for pastebin and other text uploading sites.
This test version should fix the height problem. Let me know how that works out.
The brightness difference is probably because those trees are using object LOD while the other trees are traditional tree LOD - in conjunction with ENB or weather mods. In vanilla setting the it seems fine, but a small difference might be amplified in other circumstances.
See if setting FlatLODLightingEffect=2.0 or higher in ..DynDOLOD\Edit Scripts\DynDOLOD\DynDOLOD_TES5.ini helps with that.
You could also try to manually adjust the brightness of the LOD texture used by the object LOD trees ..Textures\DynDOLOD\LOD\DynDOLOD_Flat_Atlas_Tamriel.dds but not modify the tree LOD texture ..Textures\Terrain\Tamriel\Trees\TamrielTreeLod.dds
The brightness drop down changes both equally.
Another option to have all tree LOD be done as object LOD, just like ultra tee LOD, but just leave the tree rules set as Billboard for all LOD levels.
