Better 4K image from streaming than my BD player -- is this possible?

[enro]

Does anyone have a similar experience?

It seems like I'm getting better, sharper detailed picture when streaming 4K content to my TV versus my 4K BD's.

I've had an LG 4K 60" TV and the Sony UBP-X800 for all of a month now, and watched 4K BD's such as: Inception, Terminator 2, Deadpool, and The Matrix.

The BD's look good -- some scenes are really sharp and detailed -- but when I stream for example, Bosch from Amazon Prime in 4K, or something from Netflix, it looks consistently sharper from scene to scene and to my eyes anyway, like "real 4K". With the BD's, some shots are great and others aren't very crisp, especially compared to the streaming examples.

Is there some basic adjustment I need to make? Or is just that the streaming shows are newer and shot in and finished in 4K and therefore just look better, even though they're streamed?
