Yes, with that colour showing through it seems that your frame is likely be a 1999 Caldera.
The only other options with those Dropouts and that Cable routing are the 1998 and 1999 Explosif, and rather oddly, a 1999 Lava Dome that also had the superior New (Dew) Drop "K" Investment Cast Dropouts - but that seems less likely now after seeing the colour underneath.

Is there any value in restoring the colour back to original and restickering?
I am the last person to give advice with regards to the "value" of a Retro Bike, but you would really be doing it for yourself, rather than increasing any possible future sale cost.
