Sunlight sensitivity penalty was merely a -1 to your rolls in previous versions.
In 5e its automatic disadvantage in attack rolls and perception, (i.e they have to roll twice and take the worst roll, and cancels advantage in your attack rolls) and that is a more troubling penalty in 5e for many classes in comparison.
Drow rogues could not make sneak attacks in daylight, for example (you cannot do them if you`re at a disadvantage).
In a PNP campaign is not a big deal, but in BG3 where RP is not that important and there is a lot of combat involved, the Sunlight sensitivity could be a challenge.
