Let's not conflate too many things. Maybe current deployments are in that frequency band, but "5G SA" just means the connection is legitimately 5G.
In theory all 4G frequencies will get converted to 5G, and it will be a moderate improvement. Separately 5G is expanding into the wifi arena and the ultra fast near-line-of-sight arena. But "SA" is not how you tell the difference. It will all be SA eventually.
