Well, yes and no. h.265 (HEVC) made it far better for UHD streaming to an extent. Around half the bandwidth of h.264 but 4x more pixels, so you only go up 2x bandwidth.
Now we have .AV1 and h.266 (VCC) formats which need adoption first before we can really push 8K/UHD content. Again, not 100% accurate, but around 3-5x bandwidth of h.264 but is ~15x pixels.
We’ve come a long way!
Check out the next evolution, PeLED or PeNC. Perovskite LED or Perovskite Nano Crystal.
Should oulast LED 3x+, better brightness, better contrast, way better refresh rates with less ghosting, smaller pixel/higher density, etc.
