I have a monochrometer, yes. The change will likely be between 3-4nm, depending on how hard you are running it above spec. ARG tested this diode for current vs wavelength, as well as power. See here.
When run low, 520nm diodes tend to be between 515-517. High, 522-525. Is it really that high? No. Am I picky about getting the closer to 500nm as possible? Yes.
