I don't think so, on my 41CX halfnut I found that the contrast was a bit low so I adjusted it with the functions from the Sandmath module which were initially published in HPX V1N6p8 by Michael Katz:

• CTRST [Set Display Contrast]
• CTRST? [Find Display Contrast]
• CNT+ [Increase Contrast]
• CNT- [Decrease Contrast]
  

Having a way to increase/decrease the contrast as on the Pioneers makes it easy to adjust to the correct value, but on my 41CX, once adjusted I didn't had to change it again. So I would say it's useful but rarely used.
