...It's a plasma so I'm probably a candidate for OLED, though it does seem the LCD types have gotten better.
I've owned an 50" Panasonic plasma TV for a number of years, but was shocked at how hyper realistic the top 4K HDTV's looked when I recently sauntered in to my local BestBuy store. Blown away, fairly describes my reaction. The top Sony dynamically backlit LED models are ridiculously outstanding, but the top LG OLED models are even more ridiculously outstanding, IMHO. Unlike with audio, video dynamic range expansion seems to make a very big subjective improvement. My plasma suddenly looks obsolete.

My LG plasma died last year so I went to a 4K TCL OLED. I'm no videophile, but even to me the differences are obvious. Plus the savings in weight / energy. And it has Roku built in.

What does Hi Res sound like?
For fun and education, you can:
- Load a 24/96 track into a tool (I use Audacity).
- Make a copy (Edit --> Duplicate)
- High pass filter one copy at 20 KHz, leaving only the ultrasonic sounds. (Effect --> High Pass Filter --> 20 KHz - 48 dB/oct)
- Boost the gain (Effect --> Amplify) or normalise (Effect --> Normalise) to make it loud enough to hear.
- Set both tracks to play back about 1/4 speed. (Click on each track title. Select Rate --> 22.05 KHz.)
- Press Play, and use the Solo buttons to switch between tracks.

On good "Hi Res" material, the ultrasonics are quite definitely "musical". On poor or upsampled material, they are various forms of noise.
