Of course it matters, even if you're not printing in fluoroscent. A spectrophotometer that measures only visible light is going to measure a different colour if the light shining on the test surface includes UV. If you're trying to get the best possible match to a fluoroscent colour on a non-fluorescent printer, you're probably going to want to do a test print based on measurements taken with and without UV.

I1p will do UV, UV cut and D50.
My spectropad will also do all 3
My LFP will only do UV. you need a UV cut filter for it. But the accuracy on it is insanely good.
