Help with gradient resolution?

[u/MrMermaiid]

Hey guys, I’m not a graphic designer but a musician. I make very minimal cover art design for myself like this one because I don’t like thinking much about that side of things. I wanted to have a cool gradient vibe with the purple fading into the black since I usually just use full black and this is a special release. I hate however the way you can see each tone/layer of purple in this really pixely sort of way. Is that just inevitable since I’m using such simple colors, or did I do something wrong exporting and is there a way for it to look smoother?

Thanks in advance!

This is just an artifact of compression; adding noise might help.

The noise sounds like a good idea i want to try that
