Correct, the wavelength_3d is in the sensor_band_parameters group.
Some background...
The sensor_band_parameters group contains informational parameters and has been part of the L2 ocean color metadata since the days of SeaWiFS and includes a wavelength parameter that is the list of wavelengths for the sensor - not necessarily related to the wavelengths in the products... With PACE, we have a need to have a wavelength parameter that is NOT the full sensor set, so we created the new wavelength_3d parameter. This is the list of wavelengths associated with the 3 dimensional arrays in the L2 file (e.g. Rrs). We are considering redefining this parameter to be a dimensional quantity (dimension wavelength, instead of wavelength_3d, with a corresponding wavelength variable).

Sean
