If not, due to the differences in monitors, the true way to judge this is to look at the colour of fresh blood (before it oxidizes and becomes brownish).

Not true. Gubelin, GIA and AIGS are all using the term
I've seen many certs with that term.
Example of GIA "pigeon blood": https://www.1stdibs.com/jewelry/rings/cocktail-rings/gia-certified-five-carat-vivid-red-pigeons-blood-burma-ruby-diamond-ring/id-j_133980/

Make sure you have proper lighting to compare, any stones will look black when viewed in the dark.![]()
