More precisely stated, hot pixel values are replaced with high- 
probability, nearest-neighbor values to smooth the rendering. Not  
exactly "interpolated", per se. 'Hot pixel removal' is jargon for  
this process.

I think otherwise you are oversimplifying what bayer demosaicing and  
gamma correction are if you say that all pixels in the resulting  
image are 'interpolated'. The values are certainly derived in many  
ways, but the interpolation process isn't what most people tend to  
think of as interpolation from high school trigonometry.
