'No Flare' call is solely based on the annunciator. In a 74 at 3B minima you have no chance of assessing the point to flare visually.
Minimas for 3B are; -
ceiling 0'
RVR 100/100/100
Visual reference Not Required.
Approach lighting Not required
Runway lighting One centreline light
For an approach using LVP you always plan and brief the best available, so, if Cat 3B available that is what you use. This gives the ability to possibly continue if there is a degradation of equipment etc using 3A , Cat 2 etc prior to alert height and subject to the weather.
The option for a visual landing is because not all approaches remain IMC to the minima and should a failure occur at such a point it still allows you to legally land.
Over 25 years of LVO never once online have I had such a failure but certainly done my fair share in the sim.
For all intents and purposes, if you are doing a 3B approach and providing the wind remains within limits and equipment performs, then you are landing.
