Bug Description

Calibre 5.4.2 (x64), Kobo Aura HD (firmware 4.24.15676)

According to this thread on MobileRead, Kobo Aura HD uses BGRA when generating the covers on the device instead of RGB, which results in the colour channels appearing swapped in Calibre's device view: https://www.mobileread.com/forums/showthread.php?t=334708

I'm not sure if this is by design or if anything realistically could be done about it (I think it'd require both a way to detect BGRA and the ability to swap it to RGB) but it would be nice to be able to view the covers with the right colours.

Thank you!

ADDENDUM: It would also help when copying covers from non-sideloaded books on the device to the Calibre backups. Right now I have to paste it into an image editor to swap the colours first.
