Not at all, trust it entirely on clear water. The UVC tech is very effective, they've got nice technical papers on it. And it's widely used for larger scale water treatment and very well understood.
If anything, the convenience is a factor in drinking more. It's so easy that I can do a bottle on a quick rest stop by a stream. I leave it handy so maybe 30 seconds to pull it out, and a minute for the uv to shine. (For muddy water it should be filtered enough first to make it clear, but I don't experience that.)
