I did try to get a few pics, but it's impossible to get the colour of the leds right. It just looks orange no matter what colour balance I tried, so gave up in the end.
I have the same problem with mine, I've got the orange backlit keys and trying to get the spacebar LEDs to the same colour is a nightmare so I've just disabled them. I think I would've preferred that they'd used the same LEDs as all the rest of the keys instead of RGB ones.
Can't say I've had any issues with mine turning off and haven't noticed any flickering either so doubt I'll bother with a firmware upgrade, my only problem is my caps lock LED stopped working. I found if I remove the key and put some pressure on the LED it works so it seems like the connection has come loose, possibly because I was too forceful installing the rubber O-rings... I always have caps lock off anyway so I think I can live with it, annoying though!
