In your attached jpg, tde-trinity and tdemultimedia-trinity are only
metapackages; it's not going to remove all of Trinity.  But if you're
upgrading the OS from jessie to stretch, you'll have to upgrade Trinity from
jessie to stretch also.  I don't know whether Trinity for jessie will work
on stretch.
