Same issue here with a neon green wash across photos when using the lux option, I've filed a bug report with Instagram but they are not known for their responsiveness.
Seems some Galaxy owners have experienced something very similar (with earlier android versions) and there are report that turning off the two 'advanced features' worked for them, didn't work for me though (Nexus 4 / 4.3). I've tried all the usual (uninstall etc) and also have reproduced the same problem using photos not taken on my phone so it seems to be IG specific rather than an artifact of changes to the camera.
