Take a look at the FCOM, i think Vol 4 Failures and associated actions below 1000ft for Cat III approach, it gives the option on no "Flare" at 30 feet to either disengage and manual landing or a go around, firstly it is quite a subtle failure often going unnoticed, secondly trying to do a manual landing from this point is quite tricky bearing in mind you only have around 3 seconds before impact.
