Just as an aside for people who may still be confused,
ComfortLight debuted on the Kobo Glo in 2012 and is basically just a glorified frontlight.
ComfortLight Pro is the one that can change color temperature and debuted on 2016's Aura One, and according to the
Dutch listing, is what is set to appear on the Clara 2E.
ComfortGaze is a technology linked to E-Ink's color screens, and the only reason why the Internet thinks it's linked to the Clara 2E at the moment is because that
badereader guy thinks it is.
