Some research report, nothing insightful, but maybe you like to hear that your data was used for some fun :)
 
 
Greatest image reverse search number of results is returned for pure black image.  
because:  
  1. videos intensities often written as zeroes (not sure, is this some default for non-images or black first frame but I am not curios here)  
  2. there are a lot images with almost black RGB channel, shaped by alpha-channel
     
    If I filter images by only jpg/png type, the most popular image intensities are 84% (all nw/ne/sw/se), this is mostly sketches on white canvas, random examples:
     
    id:887130 OR id:1199605 OR id:710207 OR id:1973369 OR id:1342558 OR id:980837 OR id:1657132 OR id:1579694 OR id:1511092 OR id:845906 OR id:590728 OR id:2043172 OR id:879879 OR id:1311237 OR id:1289942 OR id:113926 OR id:833858 OR id:1747729 OR id:1907604 OR id:938497 OR id:1905000 OR id:1137379 OR id:1436988 OR id:156902 OR id:928870 OR id:1665760 OR id:1782928 OR id:1894505 OR id:1948949
     
    You can use any of these sketches ( https://derpicdn.net/img/view/2016/7/13/1199605.png for example ) for reverse search and get large number of results even for 0.01 fuzziness
     
    Image intensities popularity was calculated after rounding nw/ne/sw/se intensties [0.0 - 100.0] range to integers and printing the greatest count in 100x100x100x100 array

Heh, this is why my bot uses a pHash to check each possible reverse searched image until it finds one that matches.

Something less trivial. While all derpibooru arts average brightness is peaked at 99%-100%, top rated art average brightness is peaked at 80%. Also top half is slightly brighter than bottom. Actually this is not insight for artists, this is well-know rule that image top should have more space and lighter than bottom. Sorry, I can’t today make very clear illustrations, but  
full
 
I have sacrificed non-safe images, because their fave count are less about brightness distribution and more about image plot, other “quality” thresholds for fave count and they are lesser part of images overall. Brightness is taken from image_intensities database table, value 85.425 is renormalized to 100%, top brightness is as ne+nw average, bttom brightness is taken as se+sw average

I have made diagram which maps whole image luminocity to number of image faves with this luminocity
 
Sorry, no quantiles/confindence intervals (anyway, they are not very reliable for real world non-so-random variables) :/ https://imgur.com/a/LSMzirE
 
There are smooth maximums at 30% and 80%, can’t determine reason. Also there is the sharp peak a 0%
 
Peak at luminocity = 0%, these are mostly artist:brist-sta sketches with pure black RGB channels shaped by alpha - id:575309 OR id:452762 OR id:1214368 OR id:450548 OR id:797007 OR id:518545 OR id:454628 OR id:93637 OR id:777566 OR id:751581 OR id:682715 OR id:656416 OR id:818833 OR id:1044815 OR id:519373 OR id:1315209 OR id:269536 OR id:247799 OR id:248686 OR id:1529097  
This artist alone is the reason of peak of faves/upvotes for luminocity=0

image_intensities table, ((se+sw+ne+nw)/4 / 85.425 * 100)
 
I don’t use avg_intensity from database, because it is (or close to) average of other intensities, so I didn’t exported it to avoid redundancy.
 
I distribute images to 100 buckets from 0% to 99% based on this luminosity and print median or average from images of each bucket. Median works not very good for plot visualization, because it is small integer about 20-30 and gives too sharp “steps” on plot. But it behaves same way as average with extremums at same places.

I don’t know how properly handle zero values for geometric mean. Maybe just throw them out or add artificial bias (1? By why not 2 or 3 or 0.1?), but this seems to be quick dirty fix.  
I rely more on quantiles or median values for making conclusions, and use average for visualisation just to make plot line look smoother ( I work with data for plots >>1664423 ).
 
Sometimes I use geometric mean implicitly, as average of logarithms of biased value, but I don’t need it here, because usual average gives acceptable result for visualisation.
