thermal colormaps vs luminance

matplotlib's sequential maps that look like blackbody thermal color with luminance plotted in white

 

seems that none of these are really ideal. they have banding or don't extend all the way from black to white or have too little change at the extremes and too much in the middle...

 

If you also plot the R G B components, you can see that the banding occurs where they have abrupt changes in slope.
