It is uncertified, and therefore not yet Roon Ready. The certification process was introduced three years ago:
The relevant section in that announcement I suggest is this:
Uncertified devices are not meant to be sold to the public, but instead only used by the manufacturers’ development teams.
Not every manufacturer obeys the rules, thus breaking the trust the program intends to create. If you bought an uncertified device, it means the manufacturer violated the trust we wanted to create and have violated the Roon Ready license terms. We currently call out those development devices with a pink banner, as you can see above, in hopes that no user is fooled into purchasing “beta” hardware.
