I believe so that it is as it is the infrared light captured ... This image was shot on a FijuFilm X100T with a 720nm filter on the lens. The results are nice but the addition of the IR Filter means you really need a tripod shot as the light is restricted to 720nm and above.
Technique is quite simple, shoot with a Monochrome (B&W) Red filter simulation in camera and set the White Balance to the lowest possible setting, in this case 2500K. You can also use the RAW for a false color emulation by switching the Blue & Red channels but because the filter is only 720nm light and above there is very little color left except for magenta.
B&W in camera ... certainly provides a different result.
