Interesting color.  Do you detect the usable effect of the purple portion?  I don't think this 17-35 zoom would transmit any usable amount of UV.

well it certainly transmit blue.... the problem is that i can't WB this correctly with the UV-VIS-IR conversion.

Judging from the transmission chart of UG-2A, it might be regarded as a light IR filter with the additional purple.  It could be interesting for the false color effect?
