However, in digital world, you can make color changes after the fact, so
there is little difference between UV and skylight.

If you shoot RAW, there isn't even a change at all, if you do color
balancing in the RAW converter. You are scaling the RAW data for the
first time, using your specific scaling as a _sustitute_ for the
default. The native scaling of the sensor/CFA is not what you get
without any color adjustments; it would be totally unusable on many
cameras, except as a special effect. On the 10D, equal scaling of the
channels would result in a very cyan cast, as the red channel is 0.6
stops less sensitive than the blue and green channels.
