Can you take NDVI/NRG infrared composites on a smartphone

i.e. without removing the infrared block filter? Above is an attempt just with/without an IR-pass filter with an iPhone 4S - you don't get that bright white color from vegetation, though, so I think this may not work.

Visible and attempted near-infrared photos:

There isn't tons of vegetation in the photo though. Maybe take a picture of a healthy indoor plant, just to be sure? I am sure you're right, but the grasses tend to shut down some processes for the winter, I think.
