Vampires and Daylight Spell

There are changes between 2014 and 2024 versions of Daylight spell. The 2014 Daylight description mentions bright light. The 2024 Daylight description mentions sunlight.

If anyone is a DM, how would you rule the spell for effects against vampires? Would you count it as affecting vampires if in an indoor location?

A Vampire would takes 20 Radiant damage if it starts its turn in sunlight from Daylight spell and while in it would have Disadvantage on attack rolls and ability checks.

I agree. The difference between 5e and 5.5e was also commented here:

Sunlight is sunlight. The spell was changed and got a bit of a buff.

Just to expand on what the others have said, the whole point of the spell explicitly defining its effect as sunlight is so that you can use it in a situation where it being sunlight matters, but where you don't have easy access to natural sunlight — such as while fighting vampires indoors.
