@pachyderm pro No, there's a netted exhibit before that one. It would be directly behind you as you took this photo. It would be hidden from that angle, though. It's only visible from either a glass viewing window in the cave area before this, or through an easy-to-miss small wire viewing window just before the elephant shrew/pygmy goose exhibit.
Birdsandbats is correct, the exhibit with the Wolf's Guenon has had a black canvas over it for quite awhile now, even before Covid. It's a shame, I really like the exhibit when the there wasn't extremely limited views. Originated as the Ring Tailed Lemur exhibit when the Lied Jungle opened.
