It's something else. They're Cherry's own flat caps which don't seem to have an equivalent "standard" cap shape.
As far as I know, noone else makes sets like that, they only come on the G80-3800 series boards. The caps lock stem is in a weird place, so you may not get it to fit nicely on a Poker. The 0/Insert key from the numpad may fit on the Poker Caps Lock, but it would look a bit odd.
The closest that I know of are DSA profile, but those have spherical indentations and are a little higher. They have a nice "vintage" look, IMHO.
