HP Reverb 2160x2160 pixels per eye. Not perfect by any means. Reverb G2 this Autumn gets the Index Lenses, Physical IPD Adjustent, Reduced Chromatic Abberation. Same Reverb FOV though. Even so, IMHO even the Reverb G1 reaches an image quality and resolution threshold for me that no HMD before it had where I can watch a Movie, Doc or TV Show and not think about Res or SDE or Blacks or artifacts. A lot of it is subjective though. I have a lower quality threshold than you obviously. I personally have no complaints about the colours of the LCD's used in the Reverb and likely Index and the same goes for blacks. I only see the 'LCD Grey' when the screen and environment are almost totally dark like end credits. The rest of the time with the environment lit up by the faux reflections from the virtual screen and with something bright somewhere on the virtual screen, the Relative Contrast ratio effect is very strong for me where the blacks look very black as long as there is something bright on screen for the eye/brain combo to work its relative contrast ratio trickery.
Obviously I can't wait till we have smaller lighter form factor, wider FOV, Wireless, 4000x4000 pixel per eye OLED grade colours and blacks, but like I said I feel the Reverb G1 has reached a threshold where VR Cinema enthusiasts can start to ignore the remaining image quality issues and compromises. I'm keeping an eye on the soon to be launched Pico Neo 2 4K Standalone/Wireless HMD. That allows SteamVR Wireless Streaming so I could do what I did with my Oculus GO last year which is stream the High Poly VR Cinema environments of Virtual Desktop HighMax and Bigscreen to the WIreless HMD except with the Pico Neo 2 it'd be Reverb level SDE/Res instead of GO's sub 720p level visuals.
Ultimately though, I feel it boils down to this. You are either the kind of person where the experience of watching a movie in a 500 seater iMax Cinema with 100 foot wide screen in the comfort of your own home more than makes up for some image quality resolution compromises with current gen VR Headsets or you are the type of person who prefers to watch a pristine image on their 55" OLED from 12ft away but which is 2000% smaller than the Virtual Cinema Screen. I'm the former, you may well be the latter. I can put up with the compromises for now. You don't seem to be able to. Neither of us will have to within the next 5 years!!
Point is, if OP has a PC with a GTX970 GPU or above and can compromise on Blacks and 4K res he can have a True iMAX 3D experience with 1080p/no SDE level visuals in the Autumn for about £700 in the form of a Reverb G2. Worth it IMHO for Virtual Cinema usage alone nevermind actual VR Games.
Then again, if he's the type of person who even hates wearing 3D glasses to wacth 3D movies then wearing a VR Headset will be a step to far and there is no saving him from a 10 thousand pound spend on 4K projectors and fancy screens! LOL.
Because the FOV is crap, the audio sucks, the resolution is terrible, and you are wearing a headset on your head.
I don't get people who say 3D Blurays in VR is amazing. Its not. Its the worst form of watching 3D films. 3DLCD, Projector and OLED are all better ways to experience it.
VR is great because its an active form of entertainment where you close yourself off from the open world and wear and uncomfortably heavy headset the promise of ACTIVE entertainment and enjoyment. The sacrifice is worth the advantages.
However using a VR headset for a passive means of entertainment is not a very good trade off for most people. The benefit of a few extra things popping out into your face or around is not worth the negatives of:
1. Wearing a heavy headset
2. The unsocial nature of now watching films with the headset
3. Being closed off from the world
4. The resolution being terrible
5. The colours and brightness not being as good as your TV
6. Audio compromise (unless the audio is being fed through to your speakers).
etc.
7. The scale is slightly off , its not perfect becaause the display isn't real
8. the FOV is very boxy both vertical and horizontal (even on valve index)
9. screen door effect
There is also a sense of awe when something projects into YOUR room. This doesn't happen with a VR headset.
There is a place for VR and 3D films potentially.. a niche one.. but with the current crop of headsets, its very much so a big compromise. FYI I have a PSVR, Valve Index, Oculus Quest and Rift S, and have tried 3D films on all of them. Its fun, but its no where near projection or TVs as an experience.
VR has a lot of AMAZING moments and wanders. RE7VR, Superhot, Astrobot, Half Life alyx, Asgard's Wrath.. I can comfortably say watching a 3D Film in VR is one of the most underwhelming. Making huge compromises for an active form of entertainment, just to play a gimped form of passive entertainment will not make sense for most people.
Remember there is no doubt 3D partly failed because people couldn't be bothered to draw the curtains, put 3D glasses on and press the sync button. Putting on a WIRED VR headset and shut yourself from the outside world in a boxy claustrophobic field of view
If we can get a wireless, OLED, HIGH FOV, HIGH RESOLUTION, VR headset which is light, then maybe we can start talking about it being a the 3D blu-ray saviour. and the sad thing is it will come.. but will it come in time for 3D blurays to still being made?.... no.
