I purchased my current TV in 2005 after just moving to the US. Its a great TV, a Pioneer 50” PDP-5050HD plasma. Amazing picture quality including a large contrast ratio that you get from plasma. Its only 720p resolution but given the size of the TV and the distance I sit it OK for now. At some point in the next few years I would like to upgrade. Here is my wishlist and I hope Apple delivers with their future TV and content service.

Cinema wide 4K (4096 × 2160), Note this is a 19:10 aspect ratio which is more pixels than traditional UHD (3840 × 2160) with at 16:9 aspect ratio. Personally I watch more movies so a wider display is better. I also want a larger TV so I don't have to sit very close to get the benefits of the increased resolution.

A bright 1,000 Nits display when displaying all white leading to a contrast ratio of 50,000:1. Todays best TV are around 350 Nits.  (BTW a Nit is the SI unit of luminance or brightness measured in candela per square metre cd/m2).  A brighter display gives a more lifelike picture and provides more contrast and colour range. In addition local dimming or OLED are also required to improve contrast ratios.

A wider colour gamut supporting ITU-R BT.2020 using 10-bits to represents colours. Todays TV use ITU-R BT.709 and only display about ⅓ of the colours we can see with our eyes. Next time you see strawberries on TV look carefully. On your current TV the red will not be correct as its is outside the gamut that the TV can display. Ideally the content will have support for High Dynamic Range (HDR) where more bits are used where they are needed just like the human visual system.

No Chroma subsampling. Todays TV content is typically chroma subsampling in a form called 4:2:0. Basically because the human visual system is much more sensitive to variations in brightness than color the color called the chroma is reduced to save bandwidth. The problem is that this can lead to artifacts especially on games and computer displays. Ideally the content would be deliver in 4:4:4 without any loss of colour.

High frame rate when its required. For a sports match 120 fps is required for the best quality. It might be better to broadcast at 1080p at 120 fps than 4K (2160p) at just 60 fps and let the TV upscale to the native resolution.

H.265/HEVC Main 10 built in decoder, with also a camera with a built in H.265/HEVC encoder for Facetime or Skype.

FInally of course I want Apps on my TV and AirPlay as well as a beautiful industrial design.
