Here a quick one with a simple Gradient texture where Color2 is set to a Dots texture.
Dots Color1 is white, Color2 is dark grey 15,15,15. Gradient texture Color1 is dark grey 20,20,20.
Also changed tonemapping to filmic medium contrast. Multiplier and Bloom post effects are also used.
Anyway, with more time you could get better results. And using _Render you’d get less banding than in the viewport, obviously.
