I'm wondering if the some of the planks that were installed were leftovers from other jobs. The texture and finish should be the same. I would have questioned it before the installer left your home. I wouldn't have made the final payment either.
I'd hit it with either Minwax Polyurethane (will yellow with time but won't show up with most wood colors), or Minwax Polycrylic (won't yellow so good over white surfaces). If you have any leftover scraps from installation, or can go buy just one board, you could try out your solutions on that and pick what you like best. I intend to topcoat my floors (and repeat as needed) because that seals out moisture and dirt and can make floors easier to clean, and last longer.

I would not put polyurethane of any type on top of vinyl; floors. I see it causing nothing but headaches and a big mess.
