Yes.Would you buy native 4K remastered material only available on standard BD? The case with many, many BD titles
I haven’t upgraded to 4K yet so I don’t feel strongly about that. SD is 11 years past, so I don’t mind putting it behind me at this point. And UHD in my limited experience is a much more modest improvement over HD than HD was to SD. So new materials are HD or UHD depending on pricing. But in five or ten years, I can imagine no longer buying HD material.
