Typically, its difficult to visualize the difference in sensor measurements purely by checking out a spec sheet. The visual underneath will offer you a better sense of the sensor sizes in the DP1 and A7R III.

Clearly, each of the cameras provide different resolutions and different sensor measurements. The DP1 featuring a smaller sensor is going to make getting shallower depth of field tougher and the Sony A7R III will show extra detail due to its extra 37 Megapixels. Higher resolution can also let you crop photographs more aggressively. The older DP1 will be behind with regard to sensor technology.
