Got to agree with Jelendeer.
I've seen how some Scottish wild venison is harvested and presented, and TBH it was disgusting.
This was on a "best practice" event, held in a Royal location, and it was an embarrassment to see the trainers having to cut away gross contamination before trying making the best of the poor carcasses during the butchery class.
We even went hungry at lunch because the caterers had to discard the majority of the meat provided, before making the venison chilli.
I could go on, I later saw some disgraceful practices on a large Scottish island. Deer shot in dubious circumstances (at night, by lamp, on quad bikes) then left to be collected next day, dragged down by the quads, and only then gralloched. I was camped in a forestry clearing and witnessed it all.
Maybe prejudiced because an ex GF comes from a family of NZ deer farmers, and I know how well they do things.
Park culls, and/or the stuff I shoot myself is what fills my freezer. If I had to buy it retail, NZ farmed deer would be my first choice. If I knew of an outlet for English farmed deer, likewise. Not interested in Scottish wild venison, I know too much about it.
