@fred but mostly all.
In the Plus versions, 'simple' shapes and fills are achieved in CSS, or in SVG, when activated.
A box with a linear fill renders the fill as CSS linear gradient.
A box with an elliptical fill has an SVG data image URL.
it doesn't really matter what these are or do but they are not dimensioned; they rely on the browser to render at any scale.
No banding. Well, less as you are now trusting your browser engine to do the hard work.
It seems a shame to destroy all this fidelity by making the end result into an image.
It you must then go for WebP, also in the Plus editions.
I had a gradient 1280px wide and saving as WebP:
I found the banding to be lessened than PNG @500%.
It is also possible to apply a CSS blur to the final image.
The SVG-rendered image was by far the best.
