Yes, it is safe to load several times the lut. You can check it using 
dispwin.

The monitor does not have any effect on the video card lut; only sofwares 
like xcalib or dispwin can load it (and screensavers!). Hibernate modes 
may also overwrite the lut. Switching to console mode, and then backing to 
X may also affect it. I think it is a good idea to have a shortcut on the 
Desktop to load the lut; so, if you have a doubt, just click!
