Whoa... What? That's a little weird. I got a guitar from them with an ebony board just last year and the ebony definitely appeared to be real and not dyed. I feel like if they had a dyed board it should have been relatively easy to spot right off the bat. The only other wood they use there remotely close to ebony would be rosewood and even with a dark cut of rosewood, I imagine the grain patter would give it away.
Sounds like someone tried to dye their fretboard aftermarket and used something less than effective.
