I disagree. The fight between Blue and Echo was confirmed on Empire Magazine. Plus, in an interview with Chris Pratt during the backstory he and Colin agreed on for Owen Grady, he says:

"We decided that the likelihood is that, in the years that he’s been working for the park, this isn’t his first set of raptors. Raptors didn’t make it through some of the training. These animals died on his watch. They killed each other on his watch. Certain techniques that we tried didn’t work. We’ve come a long way and a lot of these animals have paid the sacrifice for the work that I’m doing for this company."

Subject V-2 was probably one of those raptors that died before the births of the pack we see in JW.
