Yes, OpenBH, OpenATV, OpenPLi and PurE2 were released into the public, all compiled from the original Git sources, so all these images are from original source code, compiled by Japhar/PurE2 Teams.
Naturally, as every new image, these need some more twisting, but are already working very well at the current stage, some members prefer them to the original images... so you have no risks to use them, then if it's your type use them, or use any other image you consider better for your needs.
