Uncompressed HDMI at 1080p runs at 3.3Gb/s. It is a technology over 10 years old. Most homes don't have a single wired network connection in their home which operates at 2.5Gb/s, let alone 3.3Gb/s. Plus, using multiple channels of uncompressed 1080p, let alone 4K with HDR, wireless, and more, the idea of 'standard ethernet' being the solution is just not realistic.
I have done Ethernet-based video distribution in commercial AV. The equipment to encode 4K/60 into a real-time high-quality stream is costly. It FULLY saturates a 1Gb/s network and requires a fully managed switch with switch setup to allow the video and audio to pass properly. It also has to have 10Gb/s uplinks when multiple switches are in use.
I suppose, if people are really willing to give up image quality, then there are certain things which can be done with high-compression video distribution, but at the end of the day, a network can't handle the raw data capacity which HDMI is delivering with both 4K/60/HDR (18Gb/s) and the 8K standard which supports 48Gb/s. This is all designed as point to point uncompressed video distribution and while DRM is a part of the HDMI standard, it isn't required on all video sources, but those video sources still need all that bandwidth.
I've also seen half a dozen or more PC to wireless solutions, and while some work very well, overall they still don't come close to a wired HDMI connection. Both frame rate and image quality significantly suffer.
