There are downsides to FP as well. I am not advocating one over the other. But there is a concrete theoretical reason why FP is more modular, reuseable and organized than OOP code.

Smalltalk is possibly the only OOP language that lets objects be compose-able and modular. Check out Pharo if you're interested. If you learn smalltalk well enough, you could apply its principles to traditional OOP languages and gain the modularity benefits.

I've seen Java 8 functional stuff get unreadable.

But other than that, is there any other concrete downside?

For using Pure Functions, I don't see any downside to this. Aside from it being impossible to use for outside the program side-effects like IO to device.
