@RudhyR Use a Network Analyzer App.  It should show two 6 GHz channels with the same MLO SSID as the 5 GHz if I am correct.  There hasn't been a firmware update since January I've got nothing on you don't worry....

The program you pointed me to, at least on iOS doesn't show me that.

Doesn't matter, that is all non--Information when I want to KNOW which BAND or BANDS my iPhone is connected to under the MLO SSID.

Using Acrylic Home I can get similar info like you posted.

Here is what my PC is using when connected via MLO for instance:

See, I can tell it is connected to the 2.4 + 6Ghz bands, that is what I'm trying to see on the iPhone.

Yes, I can tell what SSID I am connected too, but unless it is on this Deco, the 6Ghz SSID and assuming the shared 2.4/5Ghz SSID is not broken apart I can't tell. Using the 3 band MLO the iPhone could be on any one of them. I'm betting it might even switch depending on how far from a Deco it is as 2.4Ghz travels stronger far from the Deco.
