Also, I'm not sure what type of UV light you used for the photo, but normally the markers and hands have a much whiter glow under UV.

Here are some examples. The first photo is a GMT 16750 tritium dial with relumed hands. The second photo is a GMT with full tritium hands and dial. The third photo is a Mark II matte tritium dial. The fourth photo is a comparison between a relumed GMT dial and a tritium GMT both being examined under the UV light.
Thanks for the extra detail Springer, cool to know its a 5B! As for the UV light, in the real world they light up almost a light green, like your final example photo on the right, the hands are also bright but a bit more white. In my photo I think the iPhone automatically like normalized something so it doesn't look very bright.
