There is no difference in the text of a spell when you cast with a racial feature and they are cast at lowest level.
WHAT LEVEL IS A SPELL IF YOU CAST IT WITHOUT A SPELL SLOT?
Such a spell is cast at its lowest possible level, which is the level that appears near the top of its description.
Spells are only scaled to a higher level when cast with a higher spell slot (PHB 201). The effect only changes if the spell's description specifically says so (i.e. a Darkness spell cast with a 3rd level spell slot still only dispels 2nd level spell).
Can you cast darkness with a higher level slot to end a spell of 3rd level or higher that creates light? No. The darkness spell can dispel only a light-creating spell of 2nd level or lower, no matter what spell slot is used for darkness. Similarly, the daylight spell can dispel only a darkness-creating spell of 3rd level or lower, regardless of the spell slot used.
Added note: the only racial spells that scale don't use spell slots to do so and are certain cantrips like the ones you could get from the High Elf Cantrip feature (PHB 24). Some include Fire Bolt (242) and Poison Spray (266) which include text "The spells damage increases... when you reach 5th level..." This is based on your character level so these spells would scale.
For your specific case, drow do not get any of these spells.
