Yeah you're right, in particular anything shot on film shines on 4K, digital, it's alright but not like you say not too much better than the Blu-ray

Blu-ray is for me the physical media I can fully enjoy and will collect for a long time I think. I can appreciate 4K UHDs just fine, but most things are still great on Blu-ray and potentially always will be

Hopefully that will keep up and there won't be a limit or something placed posthumously. Also means you are relying on the store to be active to play them in 20 years, but that's the nature of games now I suppose
