Mike,

I would answer in the same fashion: what is the wavelength you are interesting? If it is the quantity measured in the observer's frame, then it is consistent with the frequence measured there. But if it is about "real" wavelength from the absolute frame, then - not.

What did draw my attention originally was that you was interesting in the photon energy, and seems logically wanted to estimate it from the light frequency. Let me propose the following example from the everyday life.
Let us suppose you wish to estimate the kinetic energy of the car0 that hit your car1. If you are going to relay on the damage observed on your car1, then it will depend on the speed of car0, RELATIVE to your car1. This way you will be able to estimate the difference in speed, the difference in energy of both cars, but not the kinetic energy of car0.
