[Observium] DD-WRT question

Hi,

I run Observium on my home network, so appreciate the CE Edition (CE 0.15.6.6430).

I have 2 dd-wrt based switches, and I remember when they were first discovered by Observium quite a while back, they displayed a dd-wrt logo on the device list.

This hasn't occurred for a while now, and I just was interested to know if it is possible for this to happen?

Screen shots attached fyi (hopefully they won't get stripped).

This is a very minor question (hope the "noise is okay"), but if anyone has an answer I'd appreciate it.
