Hue LCT015 does not report 'linkquality'

Hi, my Hue lightbulb LCT015 ( I don’t know if my bulb is the 9290022166 or the 9290012573A model) does not report the ‘linkquality’ but afaik it should according to the ‘supported devices’ list. The bulb has the latest firmware from Philips.

Anybody with an idea how to resolve this?
