Anyone else underwhelmed by 4k blu ray disc?

So I've waxed out on a shiny dolby vision 4k blu ray player (Panasonic 350ex or something), excellent picture quality Philips 55OLED706, then the £20 odd per film, but surprisingly, I'm actually finding 4k streaming on Netflix better quality (on the rare occasion I actually find something on Netflix with dolby vision / 4k uhd).

Something like Altered Carbon or the witcher for example looks absolutely jaw dropping on built in Netflix app.

Then I watch 4k blu ray like westworld (with dolby vision on) star trek trilogy, planet of the apes, and I'm asking myself sometimes if it's even in 4k, checking the input... But my tv says its getting 4k signal even with 1080p blu ray. Dv is only 4k though right?

I suspect this is maybe due to the disc content I'm watching, maybe not actually shot in 4k. Nature documentaries eg blue planet do look good, but maybe not even as good as Netflix shows above. And that BBC stuff used to be reference material.

Is anyone else finding this?
Used blu rays cost basically nothing in comparison.

Can’t say I’ve found this, although the 4k content I get via the Apple TV is impressive, it isn’t as good as disc based media. The biggest difference for me is audio quality, mainly noticeable because Atmos isn’t ‘true’ Atmos via streaming.

I’ve been consistently blown away by the quality of some 4K discs on my CX.

Likely the reason it’s still showing as 4k but with HD content is something is upscaling, either the TV or the player itself.

Yeah I've turned off up scaling but the info bar on TV still says its getting 4k. Tbh though, if I can't tell, then goes without saying I'm not impressed anyway haha.

So I've heard a few people with discs say they should be better pq and audio, that's why I went this route.
Have you ever streamed the same film then also watched the disc version?

Isn't imax just sound? So the discs don't have dv? Man that suCks I have those discs for like £100.... And Disney plus. Lol
