The Roon page that you have shown below shows the true Roon Ready stataus.
The Klimax DS probably shows up as Roon Ready (uncertified) because it includes the Roon SDK in the device firmware, presumably so that Roon can certify it. However, until it is certified by Roon (and thus appears as such on the Roon Partners page), then the device will not function as a Roon Ready endpoint.
The DS can not be assumed to be Roon Ready just because the DSM is certified Roon Ready.
You will just have to wait until itis certified by Roon - but you will not be able to find out when that might happen. Roon will not tell you.
The post below and the thread that it is a part of, posted in relation to a similar issue with Denon/Marantz AVR’s explains further:
