Got the files - thanks, but you're probably not going to like what I have to say next
The values you're seeing (I'm seeing anyway) are just how they are in the file. ExifMeta does not decode metadata on a model-by-model basis, it just shows you the "internal" (raw format) values. If you want to come up with something more friendly, you have to do it yourself by editing the getNameAndValue function in advanced settings.
Let me know if you decide it's worth rolling up your sleeves and I'll try to help.
PS - Regarding cpu consumption - yes: auto-update will consume some cpu, more or less depending on ExifMeta general settings and whether photos need updating or are already updated. I up-throttled the rate in v5.7 so freshly imported photos would have exif-metadata at the ready more quickly, perhaps I should have made it configurable - under consideration..
Cheers (if possible),
Rob
