Placing Latin and Cyrillic legends in a single row makes it difficult to focus on the one that is relevant for the user at a particular moment.
The font used for Cyrillic is not a natural extension of that used for Latin. Letters are out of proportion, Й looks like a small letter instead of capital, С is just plain wrong shape, and stencil cuts in Б Ь Ъ would be better placed as in Ы.
you need 4 keys for basic iso layout, iso enter and the 1u next to it, and same with lshift and the 1u next to it. the two 1u are missing in the pictures.

KPRepublic has been stocking these for a little while after this drop came up. I got them to check their warehouse and the white koreans are like this there too. It's just blatant false advertising at this point; Advertising backlighting compatability and then half of the options aren't. It doesn't even make sense why they would be made this way. Still wondering if any black cyrilics are out there.
