Predator is only capable of analyzing and duplicating the effects of skills it devours. Great Sage's analysis skills were limited to superficial details of skills, it usually couldn't copy something based on sight.

Usually, what Rimuru did was he devoured something an used both the Predator and Great Sage's analysis sub-skills together. This is why he had to devour Veldora inside of just analyzing him from the outside, because Great Sage couldn't do it alone.

Predator evolved into Gluttony, and later into Gluttonous King Beelzebub, but the increase in analysis was never really stated because the power-ups of the skill were more focused on allowing Rimuru to devour more than what Predator could. Food Chain allowed him to analyze skills of those he's attached to though.

Great Sage on the other hand evolved into Wisdom King Raphael, and as a result its analysis skills sky-rocketed, and it finished the analysis of Infinite Prison in a fraction of the time. Veldora even mentioned the analysis was on schedule to take hundreds of years, but Rimuru annihilated that time table by evolving Great Sage into Raphael.

What Dxf is probably talking about, is that Wisdom King Raphael eventually gets to the point it can copy even unique skills, just based on sight. That skill however only appeared much after Rimuru's battle with Hinata, so it appearing in that fight is making Rimuru appear stronger than he did in the WN at that point.
