My handbook (MY23) says that 4/4 is "full", 3/4 needs 250ml, 2/4 needs 500ml, 1/4 needs 750ml, therefore implying that 0/4 needs 1000ml.
On the working assumption that the oil capacity of the car is significantly more than 1000ml, the display would appear to be like a digital dipstick, which has minimum and maximum lines on it. Anywhere between the two - I assume - is OK. It could be bad news to drop below the minimum line (0/4), equally it might be bad news to go above the maximum line (4/4).
On a physical dipstick I tried to keep between the min and max lines, never going too close to the minimum and never going too close to the maximum. If it's your habit to fill above the maximum line on a physical dipstick (i.e. 5/4) then you may wish to try it, but in the absence of any further information I don't think it's a good idea.
