Since Ricoh GR II's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon D7000.
Below you can see the D7000 and GR II sensor size comparison.
Nikon D7000 and Ricoh GR II have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
