Discussing the aesthetic quality of the meat is rather missing the point of the op.
In UK we have regulations to make meat production more humane.
Methods regarded as inhumane have been permitted, but only on religious grounds, otherwise it was and is illegal.
It used to be the case that we could assume humane slaughter unless we chose otherwise for religious reasons.
That choice has been denied us, and we now have no way of knowing.
The law of the land has been changed without any democratic procedure.
