Well I have just made the test with the latest SDK and it seems that qhy6 does not support live frame, here are my results:

nmac@nnnnn-Linux:/usr/local/lib$ ls -al libqhyccd.*

libqhyccd.so.21 => /lib/x86_64-linux-gnu/libqhyccd.so.21 (0x00007f86e9f60000)

INDI is pointing to a different place: libqhyccd.so.21 => /lib/x86_64-linux-gnu/libqhyccd.so.21
I have already replaced this symlink to the SDK one and the results are exactly the same.
