That is fair, though not a negative for many. Clojure prefers immutable data structures and functional constructs. Rich Hickey even wishes that he added fewer OOP constructs in the language (such as structs) and leaned more heavily on Clojure rooted functional concepts like 'transducers' which came later in the life of the language.
What would be those potential features of Lisp that Clojure is missing?
Multi paradigm support, low level / C interop capacity, really any sort of native features
Clojure is a multi-hosted language. Clean native interop would be nice to have I agree though.
It steers you pretty heavily toward functional programming.
