For my specific setup, the hot water from the sink is hot immediately if I’ve already been running the dishwasher. So, just by that, I’d assume that clearing out all of the cooler temperature water by pre-running the sink could provide some benefit. As to whether it makes a substantial difference or not, I don’t know. I’d say it’s certainly possible though.

This is the correct answer. Turning on the hot water before the dish washer starts clears out the not-too-hot water that was in the line. They don’t use that much water so it apparently makes a difference.
