If you could afford a newer TV Dolby Vision, HDR, Dolby Atmos is absolutely amazing. I’m not sure if you can pick up on the resolution in a photograph of uploaded. But even when you go to take a picture with your phone off your TV it comes up HDR and Dolby vision if your phone is capable of it and HDR.
If you’re into playing games with an Xbox or a newer PS4 Pro HDR gaming and 4K is absolutely amazing also. You can’t find many 4K TVs that are Dolby and HDR capable now for under $700 in the 55 inch range.
