Thanks but as far as I can see you can only open one image at a time in Karsten rather than a grid view to see the focus point in all the images at once to be able to grade them,
I missed the part about wanting to use the focus point display for culling/sorting...
I would recommend against that; certainly not as a primary discriminator over a close inspection of actual focus. There are just too many times where the focus point information isn't useful/accurate in relation to actual subject focus. There's a lot of reasons for that, and it varies a little between camera models, but it just isn't that reliable/good for action photography. I basically find focus point review to be pretty useless unless I am trying to figure out a possible issue.
E.g. in your example grid it shows focus "on the bird", but that means nothing in terms of DOF and the focus being where you actually want it (head/eyes). Similarly, there may be many times where the camera reports no focus, or focus on the BG, but the subject is actually in focus.
Here's some examples I was able to find pretty easily (it's harder for me to find images that are not reasonably sharp as I don't usually keep them)
In this pair the first shows no focus point/area but reports focus in the exif; and the subject is in focus. The second shows the focus area selected as in focus but reports out of focus, and the subject is actually in focus (plus, a camera can't actually use/focus an entire area).
This pair both show and report focus on the BG. In the first image nothing is actually in focus, and in the second the subject is in focus.
And I have seen plenty which show the focus achieved on the subject/eye/etc; but the subject is not sharp, either due to misfocus or settings.
(I realize focus is hard to discern in these resized screen grabs)
