Then please tell us the official definition of what a RPG game is and cite your source and why that is the OFFICIAL definition. Point is there is no official definition and therefore it is subjective.
The most critical aspect of a cRPG is choice and consequnce, is it not? How decisions fail to impact Geralt or the story or opposing decisions have the same impact (thereby making the decision inconsequential), those have been well-covered, so we'll skip them that have been mentioned and are of the Indiana Jones Syndrome. Instead, we'll go to the truly ridiculous, something I saw in a review.
White Orchard. Geralt and Vesemer face off against the griffin. Fight starts, but you realize Geralt is way too low-level to face the griffin. So you light out, you know, to survive, leaving Vesemer alone to fight the griffin. A pretty heavy decision, role-playing to be a coward and leaving him alone to fight that monster. You go do quest after quest to get leveled up. No matter how long it takes you (days or weeks in game-world) Vesemer is still fighting that griffin. No impact to you fleeing; neither in the long-term or short. One or two things should have happened. Either Vesemer defeats the griffin (at which point the game can continue, and if this were a real RPG, no one would have anything to do with Geralt) or the griffin kills Vesemer. If Vesemer dies at this juncture, the game is going to be quite messed up. Left in an unrecoverable state. So I can understand why CDPR allowed Vesemer vs. the griffin to be a never-ending fight with no victor, but right there I just lost all respect for TW 3 as a role-playing game.
In that same vein, only a few times can you take off and have that taking off impact the game (Ciri in getting her revenge for example - you'll get a failed mark in the subquest for not following her to the Golden Sturgeon, but she's still there no matter how long you take). Oh and with Yen, in the boat. Dive and swim to that island where the rocks are interesting, and she'll take off on you, resulting in a failed romance quest.
Reputation is another. Loot in front of guards, take off, come back. Everything is okay. You're not marked as a thief. Do whatever you like in Novigrad, the witch hunters will never come after Geralt and burn him at the stake, not even if you run all over the city killing their members. Sucking the spirit from that garden in Skellige really makes no difference beyond Skellige folk bitching about it. A more realistic reaction from such a Viking-based society would have been Yennefer and Geralt getting gutted because of what Yen did.
There are, like I said, numerous examples of non-impact and getting railroaded into something. They have been well-covered, so for the sake of not being redundant, I'll stop here.
Yes, there are some decisions that have impact, but not enough for me to consider TW 3 more RPG than a simple action game.
