It works, but there are other levels of the stack between low level decoding HDMI and the "smart" parts.
Without updates you might miss out on other improvements like decreased input lag, support for another format, and bugfixes for the existing implementations (i.e. the HDMI decoder strobes when specific configuration X is utilized).
