No, nothing happened. In both cases, when they saw I had my CC, it became a non-issue. Someone accidentally sneaking a peek of a concealed weapon is by no means brandishing it, and (most) LEOs should be able to recognize whether you were attempting to show it off or if it was an innocent accident. Motorcycles are particularly hard because even with a motorcycle jacket, it is very easy for it to become exposed at any speed above 40mph. I usually pocket carry my LCP on my bike now.
