Could be "high shine" or platinum. Kinda hard to tell in pics unless you can see them side by side because as mentioned lighting etc plays a role. Does look very light colored and that black pupil means it isnt albino so if you have the money and tank space maybe pick it up? Worse case scenario its a good looking healthy silver and best case scenario you get a gem of a fish for a fraction of the cost (assuming store doesnt have it listed as platinum and want a gazillion dollars for it)
I have seen a lot more albino and platinum aros lately. Did they figure out how to breed that gene or something? Used to be a couple times a year id see a platinum aro. Only time till they get it right I suppose there are plenty of "platinum" fish they breed already like bettas etc
