They are the same torch, in my opinion.
The tips on the torch look white, so it will really look differant depending on the lighting its under + camera settings. Im going to assume you are probably having it under warmer lighting which will make it look appear more yellow.
You could probably replicate it, if you run cool white LEDs instead of Warmer LED, use a yellow filter with polarized Lens, and ran higher UV a royal blue LEDs. White tips on a torch will reflect certain colors from LED and appear differant tank to tank.
Honestly most corals are going to look differant tank to tank. Unless you replicate the conditions completely, you will almost always see some sort of color change.
