The reason that looks more like Paramonia than the NnT screenshot is because that’s exactly how the platform originally looked.
There’s strong resemblance to a fallen or uprooted tree in the original version, compared to the more solid rock platform in the NnT version.
That said, I think judging the entire aesthetic of the new Paramonia based on a single screenshot is a bad idea. It’s pretty likely there is still a lot of tree roots and mouldy wooden structures in NnT, and the area in the screenshot was redesigned for a specific reason.
