I don't have any hard science for you, but I have noticed that iPhones do a significantly better job at filtering infrared compared to the Android phones I own (mostly older Nexus devices). I typically use an Android to see if LEDs are emitting instead of my iPhone because it's so much fainter on the iPhone. The photo in my article was taken with an Olympus mirrorless camera.
