Here's a question for those with the experience to know the answer:
Can upscaling a disc ever look as good as playing it back at its native resolution?
e.g. if you play back a DVD or 1080p blu-ray on a cheap 2160p screen, either via an upscaling 4K blu-ray player or by using the TV's upscaling, you will notice some artifacts of upscaling, such as blurred background characters, fuzzy edges, unnatural-looking skin, but you won't get this if you, for example, play a 1080p blu-ray back on a 1080p screen.
But... if you spend a lot of money on a top 4K blu-ray player or a top screen, can you get really good results from upscaling, such that you won't be noticing the aforementioned artifacts?
Note: I'm not asking for advice on what to buy: I'm just asking a theoretical question to try and understand the technology better.
EDIT: Just an additional side question: is there a 4K blu-ray player that will display DVDs with black bars at top and bottom rather than upscaling it?
