Quality difference between BluRay 4K and Streaming

I'm sure it's much more noticeable on a projection screen.

But I have a 70 inch LCD, and I almost never observe issues with the picture. I was actually disappointed when I got a UHD player there was not a noticeable difference in the image quality.

Which TV do you have and how far are you sitting from it? I’m curious why don’t see much of a difference.

Currently, I'm using a 2017 Vizio M series. I sit probably 8-9 ft from screen.

The biggest difference that you are missing is actually the colourspace between physical and streaming. IMHO.

I don’t think streaming is using 10-bit DCI-P3 colourspace, which the Vizio I calibrated last year can’t do a full P3... perhaps (this is a big maybe) that’s the reason you don’t see much of a difference between the two.

I do agree, however, in many cases the differences can be minimal and acceptable.

On my setup streaming doesn't even hold a candle to disc quality. Banding, macroblocking, and lossy/overly compressed audio is already bad enough without having to deal with frame/bitrate drops and stops. Granted my ISP isn't too great but I do live in a metropolitan area and I am paying for a decent speed.

And given how this all pales in comparison to the fact that I don't actually own anything with streaming I just don't see why you'd ever want to stream, if you really care that much about film/video.
