Unity 5.2 issue! Lightmaps are blocky on iOS

My lightmaps look as they used to in the editor, but in my iOS builds (iPod 5th Gen) they render as if point sampled (no filtering / blocky). This only started happening since upgrading to Unity 5.2.

Has anyone else seen this?

Here are screenshots of the lightmaps as they appear on my iPod. View attachment 154132 View attachment 154133 View attachment 154135

I mean.. it's a look, I guess... It kinda fits with the blocky theme of the art.. but... ya, I'de rather find out...
