A number of Canon EOS cameras have aftermarket, official focusing screens, for instance the super matte ones for manual focusing with fast lenses.
These focusing screens change metering, but the cameras that support them have metering profiles for their focusing screen.
Could similar profiles be implemented for cameras that don't officially support them, such as the 7D, for proper light metering? (The 7D Mark 2 does support a super matte focusing screen, so the same values would work fairly well for an Eg-s screen adapted to the original 7D for instance)

Hello, I have something going on with my recently purchased second hand 7D that I don't know whether it's a curse or a blessing. Namely, it comes with an eg-S focusing screen adapted and already installed, which means flawless manual focus but incorrect metering on anything brighter than f2.8 and anything darker than f4. Does Magic Lantern have a tool for accounting for that on the 7D?
