Rotech (Denmark) was responsible for bringing a new vernacular to the ink jet dye sub industry - Stability
You may remember the days of highly unstable sublimation ink, where "settling" (dye falling out of suspension) and inconsistency of color, from batch to batch, became a moving target and made repeatability of files nearly impossible.
I enjoy a challenge, but the unstable ink was enough to bring myself and others to the brink of abandoning the ink jet dye sub process altogether.
Naturally, many suppliers flocked to the highly reliable ink and some were suspected of selling Rotech, under their own name; Tropical Graphics (ArTainium) being one.
In answer to your original question, there are no major differences between the two inks.

What's in a name?
I spoke to a representative of U.S. Sublimation, (owners of the Rotech Digital "brand name" in the USA), who was kind enough to give me the straight story.
Rotech Digital (Denmark) does not (and never did) make their own ink, although they did develop a strong "brand name" in Europe, which U.S. Sublimation purchased the rights to, for their own United States operation.
Sawgrass Technologies (ST) now owns the European Rotech Digital moniker, although U.S. Sublimation still owns the name in the U.S., which of course, is a sore point to ST. So much so, that there may be a lawsuit coming, in an effort to wrestle the name away from U.S. Sub.
U.S. Sublimation, due to U.S. patent infringement outcomes, is still limited to selling to the large format market in the U.S.

That's a stipulation, due to the U.S. patents, (held by Sawgrass Technologies), not necessarily being upheld in court, but in keeping with the arrangement U.S. licensees of "the process" have signed onto.
Has nothing to do with the ink being suitable for small format printers.

I'm not a lawyer and I've only played one, once on TV. :-)
I'm not sure if Rotech, sold overseas, will continue being sold to the small format market or not.
As of now, in the U.S., only ArTainium (and until the Texas Original Graphics (TOG) case is settled) and TOG's Sublibrite ink are the only two brands, of which small format users can buy bulk ink (in bottles) for use in bulk feed systems, or to refill their own cartridges.
Rumor has it that, at some point, ArTainium may only be available to small format users in mylar bags, which is the form Sublijet (Sawgrass) small format users buy their bulk ink. The mylar bags are a component of the Sawgrass "Quick Connect" system.
