If you can’t see that 4K streaming images are compressed and have huge quality loss it’s you who should get your eyes checked.
I have blu rays,4K blu rays and 4K streaming and I can tell all 3 apart distinctly. 4K streaming just isn’t up to snuff because of how much they have to downgrade the image AND sound.
Just because you achieve 4K resolution doesn’t change the fact the image you are seeing has been degraded and zapped of its details to get to that resolution.
You’d have to be blind not to see it. I’ve been stunned by my 4K blu rays. I’ve never been stunned by 4K streaming because it isn’t impressive.
