Yep, surprisingly so. In fact that majority of callbacks were more along the lines of EU easter eggs. Chewie's age is never stated on-screen in the OT for instance, nor is Sabacc mentioned, or that fact that it's a card game. All of the biggest aspects of Han's character in the OT were largely ignored by "Solo" minus his acquisition of the Falcon and meeting Chewie of course. But it is an origin movie of sorts so the whole point was to show him acquiring his signature ship and co-pilot.
I was expecting eye-rolling callbacks along the lines of Jyn bumping into Walrsuman, Han saying things like "kids? no way, I bet having a kid would be the death of me" or going for the super low hanging fruit like his first meeting with fan-favorites Jabba, Boba Fett, and Greedo. The number one "past" action of Han's from the OT was him dropping Jabba's cargo, an action that plagued him through all three films and yet they made a prequel that didn't even touch that event.
