If I decide to try some different paper for my photo prints, I print a sample, send it to the paper manufacturer and they send me another icc profile to use.
When photo printing to paper, the paper is the final substrate. Papers from different manufacturers will produce different results, different types of paper (matt or glossy) will provide different results. An ICC profile for each one is a necessity.
With dye-sub, the final substrate is the t-shirt, or the mug, or the coaster, or the placemat. The paper acts solely as the transfer medium for the ink. A high release paper will release more ink quicker than a low-release paper, and a high quality paper will hold the ink better for sharper results than a cheap paper. Generally, however, the paper doesn't affect the colours of the ink as much as the final substrate. For instance, a low release paper can deliver the same amount of ink as a low release paper simply by increasing the time and/or temp of the heat pressing stage.
While you may benefit from a different profile for different substrates (a different one for coasters than for mugs or t-shirts), you generally don't need a different profile when using a different transfer paper.
Most people seem to find that "close enough is good enough", and they just use a single stock profile from Sawgrass. I'd rather make my own depending on the job. Trial and error is the best teacher for each individual.
