There is software you can download -Musicscope, for example - that will analyze the track and provide a visual summary of the ultrasonic - high-res - content of the file. There are others, I am sure.
I dont hesitate to purchase hires tracks from the growing number of reputable and visible sites who sell them. Whether I am able to actually tell the difference between a high-res file and a standard redbook version is another thing entirely. Recently produced music (last ten years or so) can sound very good in standard resolution.
HDTracks has a free hires sampler that will help you decide if hires is for you.
I am not associated with them. Just a customer sometimes.
