If it is a special bottling it will be made quite clear on the packaging, stating somewhere or other "1 of 15,000" or "limited bottling" something along those lines anyway.
If it is the Standard but in a presentation package, it belongs to the Diageo plc group, check their site for more info, but according to the Malt Whisky file it has a rating of "7 for sweetness & 3 for Peatiness" & here's the blurb.
Colour - Amber with pale gold highlights.
Nose - Quite light & delicate, medium sweet, grassy & hay-like with a soft smokiness: water gives red apples, honey & beeswax & some cereal notes.
Palate - Medium-sweet with quite good body, fragrant, nutty with a heathery floral note, quite fresh & smooth with an oily oak unctuousness.
Finish - Rich & enjoyable, if quite light, with a bit of spice
Notes - D.o.b. (Distilleries own bottling).
But at the end of the day so long as you enjoy it, that really is all that matters.
