I think that looks fine for embroidery, but I think a lot of embroidery just looks "fine"
Tech shirts with lots of text always just look fine, if you want it sharper do it as screen print or transfers.
But with that aside, if your machine has sway or swing (stitch compensation) to make it sew thinner I think that could be helpful
Also saw this post just today
https://www.instagram.com/p/DM-lXt5uOTs/ that illustrates using the same digitizing and a different needle, so could try a smaller needle as I think if the text looked less bold then would get better results.
I had similar problems a while ago where the digitizer sew outs was way thinner than the ones we would do, and it was the compensation setting at the machine level that made the difference. I'm sure it could be compensated for in the actual digitizing as well. But thinner needle could be what could make the difference.
