I don't know why anyone cares so much about Wi-Fi 6E on iPhone. Yes, it's a plus, but whoop-tee-doo.
Really, most Wi-Fi AP's still use Wifi4, and I've only just upgraded to WiFi6 in my home, and that's only in some rooms as only recently has it begun more mainstream.
What's more, when using a phone, can you honestly tell me if you can tell any discernable difference between WiFi5 and WiFi6? I certainly couldn't when I upgraded to AP's in my home. (I have four Ubiquiti AP's across my home. Two AP-LC-LR's, and two AP-A6-Lite's).
The WiFi6 AP's connect at 1.2Gbps when in direct sight, and the WiFi5 AP's connect at about 890Mbps.
I cannot tell the difference between the two when it comes to day to day usage. I can't even tell the difference on my MBP M1. Or my iPad Pro. Even my wife asked if I had installed the new WiFi6 AP's as she didn't see a difference.
So, to cut a long story short, why does it irk so many people? I don't get it!
