I chuckle when I look at old Disneyland photos from the 50s and 60s because it’s a concrete jungle, very few trees, very few plants, very few flowers, literally concrete and dirt everywhere you look, and despite the berm you can often see the exterior powerlines.
The “park” portion of DL park took decades to reach the magnificence it is today.
Having said that they took still great pains back then to hide the buildings from day 1, modern Disney has sadly lost that. In a decade the trees will probably obscure much of the show buildings we complain about today but it’s a shame that’s the new normal.
