The perspective selector dropdown doesn't look well integrated in the left lateral menu. This is not aligned with the designs available in the mockups nor the standard layout in OCP.

There are two design options: The one available in the mockups with a black dropdown inside the grey left menu, or the one that OCP proposes with a grey dropdown seamlessly integrated in the left menu. Any of them would work, although it would be desirable to maintain the design in OCP.
