I have made new findings.
The interface offers to select the preferred 3d mode: same as movie, over / under, side by side. This is found under Settings > System > Video Output.
There is another setting to select the 3d mode when starting a movie. I don't want to be prompted so I select "preferred mode".
If I pick over/under or side by side as preferred mode, 3d will kick in. The problem is when preferred mode is "same as movie".
I have a workaround for now, although I would rather use the original packed image format as is if I could. I generated another log with a working preferred mode:
hastebin
The autodetection does not seem to work. Or maybe there is mismatch betwen the tv display modes and the ones found by kodi? I will continue playing around when I have more time.
This is with preferred mode "as movie".

Which is weird because with my other tv I used "as movie" without issue. Since the screen is cracked there is not chance I can verify
