As far as I can find, EASA says:
(a) The controlling RVR should be the touchdown RVR.(b) If the touchdown RVR is not reported, then the midpoint RVR should be the controlling RVR.(c) If neither the touchdown RVR nor the midpoint RVR is reported, then NCO.OP.210(a) is notapplicable.
And
Where additional RVR information is provided (e.g. midpoint and stop end), this is advisory;
such information may be useful to the pilot in order to determine whether there will be
sufficient visual reference to control the aircraft during roll-out and taxi.
And
However, for aircraft manually controlled during ‘roll-out’ EASA
recommends the following RVRfor the MID and/or END:
