I remember my old android phone would pick up IR as a purpleish color: https://qph.cf2.quoracdn.net/main-qimg-d8d68a82c1ec4b4975b8e...
I wonder if it's possible to make it bright enough to blind regular (non IR filtered) cameras too?

With better noise reduction algorithms, more sensitive sensors and lower noise sensors, IR filters are now almost always used in smart phone cameras.
My guess would be that something bright enough to wash out the red channel would still leave the blue and green intact. So there should be enough information that the image is degraded but not necessarily blinded.
But I could be wrong, depending on how independently the color sensors and processing work.
