It was fun but I messed up the statistics! I had Redshift running, which (maybe you know) makes the colors more reddish. And I got a bluer than 98% of the population result. Turning off Redshift ... makes me instead greener than bluer.
I would guess the hackernews crowd has a higher percent of bluefilter installs since that is a very common topic. Probably also more agressive settings for the blue filter.
