Sounds like just a brand name, so they can claim it is better & can charge more money? There is no official fuel by that name, so no one can really help you.

Diesel #2 is often cheapest, has the best efficiency for summer & hard pulling. It will start gelling below 20 degrees tho, for sure below 10 without additives.

Diesel #1 won't gel in winter (to -60 or something...), but it is more $$$ and has less power, causes the engine to heat more so needed in cold climates, not so good to use in summer.

Often winter diesel fuel is a blend of those 2, put together in a blend apporopiate for your current winter conditions.

A fuel additive such as Power Service can help regular #2 work ok in cold weather down to minus 10 or so. For colder, a blend with #1 included is best.

Off-road diesel fuel and on-road diesel fuel are all the same exact thing made from the above blends. Off-road has a red dye added to it and no road taxes paid on it, the other undyed fuel will have road taxes paid on it. But, _exact same fuel_ made of the above components.

Name-branded fuels, trademarked, as you mention are still #2 and/or #1 diesel fuel. They might have a bit better anti-wear and anti-fouling additives in them. (Basically the Power Service, or etc., additive already in...) But who really knows for sure, mostly marketing hype.

Sure, you can run the trademarked name. I'd want to know what exactly it is, mostly #2 if it is run in summer, some blend close to 50/50 if it is cold. The rest is nice additves I suppose, but probably more marketing than value?
