If it doesn't say SSEi or SSE on the doors and trunk lid, it'* not either unless it was debadged. Is it Supercharged? I'm guessing not from your description, so:
Are the fog lights spaced out at the outer bumpers? Probably not closer together below and to either side of the license plate? I'm assuming you don't have two exhaust tips, one on either side of the rear bumper skirt, but rather you have a single hidden exhaust? Sounds like you have an SE to me from the limited information, but it might have the SLE package. Look for a grille that has a honeycomb insert, rather than 'diamonds'. Look for the RPO code "H4U" on the cover to your spare tire. That would be an SLE package on an SE.
