Inoue is still too far from Pacquiao's achievement. Though undeniably he's got skills, speed, and power, but he still needs to step outside his territory and beat future hall of famers, fight in catchweight since he has been dominating on his current division. Well, I guess the boxing association are protecting his value. It would be less interesting to watch an Inoue fight if he'd lose to a stronger fighter. Unless, he's got enough charisma like Pacquiao who could bounce back and fight like he didn't get knocked out cold by Marquez. That's the downside of being an undefeated fighter, one defeat might change everything and winning everything back might be another difficult path.
Definitely, though Inoue is an exceptional boxer but he is nowhere near to Pacman in terms of achievement in boxing. At his age, I think Pacman had already achieve lots of belts in different division, but Inoue stays in super bantamweight although he had unified all the belts already. Another thing that people does't admire on his is he keeps fighting in Japan, and even the "ban for life" sanction on Nery has suddenly been lifted just to give way to his fight with Inoue which is expected the champion will easily beat Nery.
