I think you are slightly miss-understanding what is being said in regards to a damp and wet runway.
DAMP The surface shows a change of colour due to moisture.
NOTE: If there is sufficient moisture to produce a surface film or the surface appears reflective, the runway will be reported as WET.
WET The surface is soaked but no significant patches of standing water are visible.
NOTE: Standing water is considered to exist when water on the runway surface is deeper than 3mm. Patches of standing water covering more than 25% of the assessed area will be reported as WATER PATCHES.
The runway can still be wet providing it is 'soaked', and there is no need for there to be surface film or reflective.
However, it cannot be reported as damp if either of these exist.
It seems quite clear that so long as the surface is 'soaked' then it should be reported as wet regardless of reflective or not.
