Short answer: no. I have two and both are shiny metal.
A few questions for you:
- How long have you had the Leshiy 2?
- How much firing/air have you put through it?
- Are you feeding it clean air? There looks to be a lot of "stuff" around the rim which has been wiped off for the second picture - only reason I ask.
