Titles that have never been released on bluray (but did have a DVD release) are still noticably better on disc than streamed. And that is a surprising number of older TV shows.

It’s not even a subjective preference thing. Any layman could identify the physical media as higher-quality in a blind test.

If you’re like watching on a phone or small tablet I can understand why you would think they’re equivalent, but in any kind of home-theater environment (even a cheap-ass one) physical media will be obviously higher-quality in every scenario.

you’re unlikely to see any increase in quality between streaming and… DVD/Blu-ray

tell me you dont care about video quality at all without telling me you dont care about video quality at all.

it is incredibly easy in a blind a/b test to pick put a streamed title vs a native bluray title. by video and by audio (provided you are using something that isnt your shitty built-in TV speakers). im not sure why youre confidently making this assertion that literally anyone can test at home with basic equipment.
