I went out with the intention of testing a 630nm filter I have, and when it came time to set the 1-touch WB, the manual didn't match the operation of the camera. In fact I tried it on both of my E-M5s, one with OS 1.5 and the other with the newer OS 1.6. Neither seemed to operate the way the manual suggested it would. What bothers me more is that I know that I set one of the MySets to the custom IR WB. It was set for use with the 720nm filter as I recall, and I know it wouldn't work perfectly with the 630nm filter, but I wanted to try it anyway. I will probably have to go back and start from scratch (although I really don't need to since I have my E-P2 out for conversion to 665nm - I was just trying to get some preliminary idea of what the result would be.
