[luatex] intercept PDF warnings

sometimes I get warnings like these:

LuaTeX warning: PDF inclusion: found PDF version <1.6>, but at most version <1.4> allowed

I use img.scan() and img.copy() for image inclusion.

Is it possible to intercept these warnings/messages? Currently they are written to the log and to the console, but I'd like to present them in a different form to the user.
