Once DVD's came out, they matched Laserdiscs in resolution. And with remastering, at times, better quality.
So there was no high-end at that time.
It's true that Bluray might not have intended to be the replacement for DVD, but it still was a newer consumer format.
Since 3D video has failed to launch also, media and hardware companies are always pushing new formats.
That's why Ultra HD BD, will require new sets, and players.
The beauty of the digital format is that, you can upgrade your monitor, projector, or TV when you wish, and gain benefit from it, accordingly.
The consumer race is over, only content creators care about increasingly high resolutions, and mastering issues.
