Probably, by which I mean the new growth will be OK; existing leaves never "recover" no matter what.
I always buy from stores, and sometimes I have brought home what many would consider almost dead plants, if it was a species I particularly wanted and had no option. But I try to get the best plant I can; look for new growth (on swords from the centre of the crown), if new leaves are appearing, the plant is OK.
Existing leaves often (usually) die on swords, due to water differences or they may be emersed forms [read more on this in our profiles on the Echinodorus species].
