For storing lossless rgb you might consider FLIF given you've demonstrated some flexibility in your setup, https://flif.info it supports 16-bit channels

Thanks for the suggestion! I tested it on one file. Support for the format might turn out to be a problem: to use the flif command line tool, I had to convert my input file from TIFF to PNG first, which means I'd have to be extremely careful not to lose metadata if I started doing this for real. It was also pretty slow.

File sizes (DNG lossless, other formats 16 bits):

* DNG: 18.5 MiB

* TIFF: 84.2 MiB

* FLIF: 55.1 MiB

So while FLIF is unsurprisingly much better than TIFF, it's still ~3 times larger than the DNG, which means that a pretty noticeable amount of additional disk space would have to be sacrificed to store the final edited versions of all my photos.

This is lossless as in it losslessly preserves an frame buffer, but it isn't lossless in that it can be edited in RAW losslessly.
