Thanks for tracking it down. I'll wait for new drivers. I boot my system only once a day (in the morning), so I can manage the 3 seconds lost per day. It's a little nuisance, but knowing it will be fixed soon, it's no problem.
Edit: a quick google on "site:nvidia.com desktop color settings" showed that this problem has been showing up since 2008. Therefor I believe that this bug hasn't been fixed for a long time. And therefor I don't expect it to be fixed soon. It might not be a straightforward bug that shows up consistently.
