Streaming Atmos on Netflix vs BluRay


This might be a total newbie question but I'm a 2 channel guy who's dabbling in Atmos.  I do have a 4.2.4 (no center) system and really enjoy what I hear on Netflix, Disney +, etc..  How much better would a 4k bluray be?

What am I missing by streaming Atmos and whatever other formats vs having an actual disc?

@dtximages...yes the joys of working from home! Just got the remastered version of Batman v Superman so I’m going to throw that on. I just upgraded my speakers to B&W 600 series in ceiling (my wife wanted clean sight lines in our living room), with the Anniversary series center channel and subwoofer. I didn’t upgrade my receiver and now I’m sorry I didn’t. I get a popping sound inside of Netflix and HBOMax when moving through the menus, very annoying.
I stream and I also rent 4K Atmos disks. I currently have a high quality 5.1.4 system that I will soon upgrade. Streaming Atmos from Apple TV+, HBO Max, Netflix and Prime, Disney is excellent. I have a fiber optic ethernet connection so speed is not an issue. When I know a movie has a very high quality Atmos sound track I will rent the disk and disks are better but it does not mean that streaming is not excellent
With my upgraded Oppo 205 the audio is way better from disc’s than streaming. Much fuller sounding, surround, Atmos, bass etc.
Actually, I am using a Apple 4K TV playing through my Oppo HDMI input. First off, I was unable to find much 7.1 or Atmos content on either Netflix or Prime. And, the few titles that are listed as Atmos didn’t sound like it.

@ozzy Thanks for your input.  I agree the Atmos titles on Netflix are few and I've heard good and bad Atmos titles on there.  However, sometimes I also wonder if it's even playing in Atmos on Netflix.  It's like my Marantz processor fails to kick on Atmos.  I just wonder how much better it would be using an actual dvd player or if streaming Atmos is "darn near the same".... I see the strong consensus is that streaming is definitely inferior.  

On a side note, is anyone else frustrated with Marantz receivers/processors and how hard it is to tell exactly what mix it's playing?  I have to open the front door to see.. I wish there was a good on-screen display available.
