Both Canon 77D and Canon 750D have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the 77D and 750D sensor size comparison.
Canon 77D and Canon 750D have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
