Here's an interesting bit, I've tried with Chromebook Pixel 2013 and
Chromebook Pixel 2015 (different chipsets) and the results are
differents

Chromebook Pixel 2013 fails to get GATT Services:

Chromebook Pixel 2015 can discover all of them: http://pastebin.com/raw/z5vr0B3P

Does that make some kind of sense?
