What type of blade do you have? We can maybe look up the factory sharpening, though FigureSpins is right - the seller might have re-sharpened it without asking.
ROH isn't the only determinant of sharpness. You can also be keen - i.e., there is a abrupt rather than rounded direction change at the tip. And the very tip of the blade can be longer. A lot of people think sharpness is only determined by ROH, because the picture the edge as being produced by the angle between the sides of the blade and the hollow curve. But sharpening initially knocks down the tip of the edge, so the keenness and length of edge aren't exclusively determined by hollow. That depends on how coarse the wheel is, how much metal the sharpener removes, and I think maybe how slowly and carefully the sharpener works. Then the sharpener pushes the edge back upright or slightly inwards with a flat stone.
In some cases the sharpener then deliberately dulls the edge a bit, making it less keen and/or reducing the tip length, because many skaters don't like extremely sharp blades, and many skaters step off ice before putting on their skate guards, or stop hard, either of which would knock the tip of the edge sideways or inwards if it was very sharp.
Carefully (don't cut yourself) run your finger along the edge, on the bottom, at the sides, and inside the hollow. If the sharp part doesn't point downwards, you have knocked your edge sideways, but it is still there. You can push it back upright with a piece of hard leather, or a rubber stone. (Most people don't do that - they just re-sharpen if anything goes wrong - but I think they use up their blades faster than they have to.)
If there is no really sharp part - your sharpener deliberately dulled the edges, or used a very coarse grinding wheel.
It's important to tell a sharpener that you want a sharp edge if you like sharp, so the sharpener won't dull the edge much if at all after sharpening, and may PERHAPS use a finer grinding wheel - if you are willing to take very good care of your blades and never step without guards off-ice.
BTW, I happen to use a smaller ROH - 3/8". I think 7/16" is most common around here, but I've met good skaters, including some coaches, who make do with larger, like 3/4", because the edge is supposed to last longer. There is no universal standard here.
