Looks like there's no green.

Does:
gst-launch-1.0 videotestsrc ! autovideosink
also show the problem?

Does:
gst-play-1.0 /path/to/those/files/
show the problem?

gst-launch

comparison of "gst-launch-1.0 videotestsrc ! autovideosink" on s390x (top) and 
x86_64 (bottom)
Comment 4 Tomas Hudziec 2017-08-08 10:39:24 EDT
"gst-play-1.0 /path/to/those/files/" plays video with correct colours
Comment 5 Bastien Nocera 2017-08-08 10:48:05 EDT
Can you please attach the actual thumbnails created in ~/.cache/thumbnails/large/ for those video files?

There's already problems somewhere in GStreamer, but let's see whether there's not another problem somewhere else.

ogv video thumbnail from ~/.cache/thumbnails/large
Comment 7 Bastien Nocera 2017-08-08 13:34:31 EDT
The thumbnail captured matches the display, so it's not a problem in gdk-pixbuf. I'll reassign this to GStreamer as that's what the problem lives.
