Yes, there is a significant difference. If you didn't see a difference you probably didn't do it quickly enough after shutdown or you may have a setup that for some reason doesn't drain back (but I wouldn't count on that)
What you can do and its outlined in the VD owner's manual I have is:
1. Verify correct oil level immediately after shutdown per the manual.
2. Allow to sit overnight undisturbed and then check oil level before the engine is run. You should find it is higher.
3. Mark the dipstick for that level.
The new mark can be used to verify correct level when the transmission has been sitting undisturbed.
On my CR2's that level (IIRC) is about 1/2" above the "full" line.
