I believe all airspeeds placarded on your airspeed indicator are "indicated" airspeeds It is true that as you climb, your true airspeed increases.

Vne is an indicated limit, not a "true" limit. The aerodynamic forces, stresses, and local stream velocities are dependant on what the airplane is sees -- and it only knows about the indicated values. So it should not be possible to "exceed" Vne if your airspeed indicator does not go beyond the red line.
