((I didn't know what any of this stuff was, but surfacially 4k....))
Most experts I've spoken to, on both the content side and the TV side, are excited about HDR and WCG. 4K itself didn't have anyone in those camps that excited. The common refrain was "More pixels are cool, but better pixels would be amazing."
Though breathlessly claimed as the next-generation TV evolution, 4K was anything but. Now, with HDR and WCG, we're looking at the promised evolution, and it should be a brighter and more colorful one.
