Are you sure you have an in spec copy of the Sigma 45? Could be focus error as well. My 45 is as sharp or sharper than the Zony 55 when both wide open and in the 1.5m+ subject distance range.
It gets softer getting closer, for sure, but at normal subject distances, it's as sharp wide open and likely sharper stopped down, especially at infinity.
I'll share below my own test which is totally unscientific but is why I characterized the 55 as sharper. They're both sharp enough for me honestly. This was to evaluate bokeh, which is more of what I was interested in when comparing these lenses. Focus is on the "little tikes" lettering, view the full sizes to see detail. I moved back with the 55 to try to keep the same relative subject size, but it ended up a little larger on the Sigma's image (a small advantage). I'll throw the CV40 in as well, which was shot from the same spot as the Sigma. These were taken on an A7rII.
I still have all of these lenses btw, I can't seem to bring myself to sell any of them.
Sigma 45 @ 2.8
full size
Sony 55 @1.8

And for fun, here's the CV40 @ 1.2
