Yes, it looks like the denoiser can't produce the best result with your render settings. It's hard to tell what exactly we are looking at. Try using more samples in the render dialog or if there are many light sources in the scene increase the "light tree samples" value which you can find under "Advanced" in the "Lights" panel.
