I've noticed on mine that newer leaves don't look exactly the same as older leaves.
The amount of 'ratcheting' on leaf edges can be quite different. You probably need to grow yours a bit bigger to observe this. I believe cultural differences can also change appearance. Even if it blooms, (TAKE PICS!) exact id could be very tricky.
My plant seems happiest scrambling over composting leaf litter. The original rooted section dies off, new branches spread and root (with little short roots). If limited in 'crawl space area', and thus forced to grow back over itself, the layer of dried dead stems prevents new roots from reaching moisture, and very quickly the whole thing melts. This can happen even when I've maintained the required steady, unvarying humidity.
Luckily, you can easily restart from cuttings laid on moist sphagnum if you notice in time.
