It could still bounce back. It takes a while for corals to turn around, and I'm not talking weeks.
I don't think it's too much light - you had it on the sand bed all the time, and that's where it should be. I think like you said, it might've been just been on the downhill slide before you even bought it. Or damaged in shipment to your LFS
and the damage didn't reveal itself until later. If it was brown jelly, you'd know it by know because, well... there'd be brown jelly all over it and you'd just be looking at a skeleton by now.
I had a Trachy that somehow got injured - I'm guessing a crab dove off my rockwork and used the Tracy as a trampoline. I crossed my fingers for quite a while hoping it would pull through. But at a certain point, as flesh started disintegrating off the skeleton, it was obvious it wasn't coming back. At that point I pulled it from my tank - no need to drive up nitrates as the tissue decomposed. I think you'll know it when the time comes, but it doesn't sound like it's at that point yet.
Don't beat yourself up too much about it - everyone will lose corals as you add more to your system. Some of it is bad luck, and some of it is just gaining experience on what a healthy specimen looks like to start with. One telltale sign is looking for an obvious lack of coralline algae, or discoloration around the area where the tissue meets the skeleton. If you see a white band of skeleton, that means the coral has had fairly rapid and recent recession and might be a good one to pass up.
