In order to go from 360p video 15 years ago to 4K HDR today, I have upgraded from a 2mbps 802.11g WiFi on a 1366x768 display to a 200mbps connection on 802.11ax and a 55 inch 4k television.
The experience is quite immersive and well worth the upgrade that happened very progressively (WiFi 5 1080p then WiFi 6/7 4K).
At the same time, we had cheap consumer gigabit ethernet, and still have cheap consumer gigabit ethernet. 2.5 is getting there price-wise, but switches are still somewhat rare/expensive.
