Why don't handheld devices have screen calibration settings?

Click For Summary
SUMMARY

Handheld devices currently lack comprehensive screen calibration settings, such as contrast, tint, and sharpness controls, which are available on devices like the iPhone. Users express a desire for TVs to automatically provide perfect picture quality without manual adjustments. The discussion raises questions about the future of screen calibration in both handheld devices and televisions, emphasizing the subjective nature of "optimal" settings based on individual preferences.

PREREQUISITES
  • Understanding of screen calibration concepts
  • Familiarity with display technologies
  • Knowledge of color theory and perception
  • Awareness of current handheld device capabilities

I mean i love having the screen set to perfect calibration like the iphone, but why don't we have tvs like that? It would be nice to not have to set anything on a tv and have a perfect picture quality. Do you think that will ever happen? Vice versa, do you think handheld devices will have screen controls (contrast, tint, sharpness ect...) in the future? (other than brightness)

The TV does not know what you consider as "optimal".

Vice versa, do you think handheld devices will have screen controls (contrast, tint, sharpness ect...) in the future? (other than brightness)
Possible.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
