the only exception from the movies was the Endor battle. Every other action we see them in is either somehting a smaller, more mobile ship would be ideal for (Policing Tatooine, chasing the Falcon) or in support of a larger ship (Hoth, with the Executor).
Endor had the Executor as well, but that's the one case where I'd argue larger ships should have been present.
Of course, we could handwave that as "the larger ships weren't shown on-screen" but it really comes down to those ships hadn't existed yet, in our world.
And before you try to make that an argument, remember the Tarkin Doctrine hadn't existed at the time SWVI came out either, but nobody's casting doubt on that…
