Interesting, that is my experience too. My social understanding has grown tremendously over the course of my adult life, but my sensory issues seem to have worsened.
I am not sure if it is objectively the case, though... it seems that way, but it is possible that I am just more aware and bothered by sensory issues because I am more aware of the triggers that make me feel bad in a situation and afterwards, how to avoid them (whereas when I was young I would had a lot of situational depressions, some of them very predictably happening, and not know what caused them).
I may also be more aware of sensory trigger situations more due to higher ambitions about what I want to do with my time overall - I avoid unnecessary sensory burdens because they ruin the rest of the day.
It is also quite possible that others' higher social expectations potentially me puts me into more overload situations, so I have to deliberately decide not to go and explain why. It is not like I earlier went to parties and was fine (for example), it is just that nowadays I actually get invited. and sensory overload has overtaken social hopelessness as the biggest obstacle in regard to social events.
