In many cases, it's hard to visualise the gap in sensor measurements only by looking through specs. The visual below will give you a much better sense of the sensor dimensions in the GR II and A7R III.

All in all, both the cameras come with different resolutions and different sensor measurements. The GR II having a smaller sensor will make getting shallower DOF tougher and the Sony A7R III will provide you with greater detail because of its extra 26MP. Higher resolution can also enable you to crop shots a good deal more aggressively. The older GR II will be disadvantaged when it comes to sensor innovation.
