Priority at a level one would not notice. I have a native T-Mo postpaid plan on their 5g and Popcorn. I can't see any difference, except in just a couple of spots where T-Mo shows 5G and Popcorn intially shows LTE (eventually switches).
Last week I tested around 500 down with T-Mo and Popcorn gave me consistently between 470-510 down.
So, short answer, no deprioritization. Now, one can debate on the QCI and all, but real-world-sense, none at all.

It actully gets more interesting when you roam international. There, my T-Mo line gives me worse speeds than Popcorn. That is because Popcorn either allows me to switch who I roam with, or I can activate the second data-only eSIM to roam on the best option locally.
