While I could have a slightly larger TV, I think that for typical domestic use 4K's improvement is marginal because people are not sitting 50cm from the screen and room sizes are limited.
Really, so far the top benefit has been that I could tell my wife: "Look, if I move right up to the screen I can still see Jeremy Clarkson's individual hair strands!"
If so, you're right; that's pretty small. Is it just a matter of acclimation?
Also, can you clarify what you mean that you're lucky to have a house? I wasn't aware of a major homeless problem in Europe.

The door by the yellow chair is a tiny porch with front door beyond. No idea how it compares with OP's.
Homes in the UK can be expensive, so there's a large rental market.
On top of that many people are vulnerably housed - living in emergency temporary accommodation (which may be for many months) or on friend's sofas.
The introduction of the benefit "Universal Credit" has increased homelessness and people who are vulnerably housed. In the UK a landlord can apply for eviction if the tenant hasn't paid for two months. (This is for shorthold tenancy agreements where tenants have most rights - other tenancies have less protection.) There is a minimum wait of 5 weeks before Universal Credit claimants get paid, which pushes some people very close to this limit. The bizarre sanctions regime tips many people over that limit.

How do you cope in a car?
But joking aside, I'm surrounded by glass on all sides in a car. That makes a great deal of difference. I probably wouldn't feel confined in a room that size if I had an entire wall of glass.
I've got a variety of content that is, technically, a video stream that decodes into a framebuffer that is a "4K" framebuffer according to the metadata on the video, but without enough bits for it to truly be "4K"; the same number of bits dedicated to a 1080P video would look just as good.
For all the bragging about how streaming is the future, it seems to me that the companies providing those streams at scale still have a lot of incentive to cut the bitrate back so far that it's not practically a 4K stream anymore, because 95%+ of their audience can't really tell.
