More exactly: The colouring algorithm makes use of additional data from
the orbit to produce a seamless colour gradient. (I.e., it doesn't just
blur the lines in the colour gradient, it actually adds additional new
detail - much like antialiasing isn't just blurring.)
At any rate, rerendering the entire frame a few thousand times is rather
inefficient. There are all kinds of tricks you can use where you reuse
pixels from the previous frame to vastly reduce the total time required
for simple zooms like this.
