Will 4K Blu-rays ever be supplanted as the definitive home media format?

After upgrading my home server to a ludicrous extent, I'm realizing I have enough room to store all my favorite movies without any need for compression, which has led to me actively seeking out a lot of 4K Blu-rays. As I've been watching these on my OLED TV with surround sound speakers, I'm realizing that I can't really see 8K or any new video format supplanting this experience in the same way that 4K Blu-rays replaced Blu-Rays (late 2010s), which replaced DVDs (late 2000s), which replaced VHS (late 1990s). Of course there's also streaming, but IMO streaming will always only provide the compressed version of media for the sake of "convenience."

I'm sure people have said this with every major home video format, but the gains in fidelity are slowing down with each format change. The jump in fidelity from 1080 to 4K can be very nice, but it's not nearly the jump in fidelity that we saw upgrading from VHS or DVD. What makes 4K Blu-rays really special is the HDR/DV that really makes the colors come to life.

Even when 8K discs are possible with newer media, unless 8K 100"+ TVs become the norm, will anyone even be able to notice the gain in fidelity? Unless there's some new technology in the vein of HDR/DV that only comes with 8K discs, which I highly doubt. VR could be the most disruptive tech for 4K Blu-rays, if people buy VR headsets to replace their TV's then maybe something like 3D could make a comeback (which already exists for a lot of movies). That is something that would probably take decades for mass adoption, if it happens at all.

On top of the lack of demand for 8K discs, how many movies that currently exist would actually be able/willing to produce make a great 8K transfer? We're already seeing those limits for 4K (expensive, lack of masters, 2K upscaling, etc.), and sometimes it leads to bad enough transfers that people recommend the Blu-ray over the 4K Blu-ray format.

IMO, if you own the 4K Blu-ray of a movie or show, then you almost always own the best possible version of that piece of media that will ever exist (excluding bad 4K transfers). I'd be very happy to hear everyone's thoughts if you agree or disagree.

TL;DR: If it happens, the leap from 4K to 8K Blu-rays will be nearly irrelevant. Almost all currently existing media will not make that leap and what we have now will not be supplanted as long as we keep using TVs to consume media.
