The answer is Yes, the disc image will be the exact same quality that you would get if you had just burned it directly from iDVD without a disc image.
You would burn this disc image from Disk Utility. This is inside the /Applications/Utilities directory.
First, you'd drag the disc image from Finder into the side window of Disk Utility, and then select it, and hit the "Burn" button on top of the window.
