In it's dreams! Aside from the difference in gamut, there's a lot of capability in the NEC that Apple can't even touch.
1. Nearly all if not all current SpectraView displays are wide gamut, Apple's are not (sRGB like gamut).
2. SpectraView uses a high bit internal processing path (at least 10-bit) with internal 3D LUTs, Apple and many other's do not. These high bit LUTs allow precise adjustments to be made to the display’s Tone Response Curve without reducing the number of displayable colors or introducing color banding artifacts.
3. Newer NEC SpectraView's use GBr LED which produce far more precise control of White Point, run cooler, use less energy, run far longer than CCFL.
4. SpectraView has 3-4 year on site warranty, Apple has 1 year.
5. SpectraView panels are hand selected from the manufacturer line (pick of the litter).
6. SpectraView has electric technologies like ColorComp, which adjusts and improves screen (brightness) uniformity using individually measured matrices for each display at the factory. All done high bit with compensation for operating time and temperature. Apple does not.
7. SpectraView has electric technologies like GammaComp, to adjust the monitor's internal 10-bit gamma Look-Up-Table, allowing various custom display gamma or Tone-Response-Curves to be achieved. Apple and many other's don't have anything like this.
8. SpectraView is a smart display system that integrates custom software for calibration including multiple target calibration's which can be loaded to adjust the display while loading the associated ICC profile, Apple (and few other products aside from Eizo) cannot do this. To quote from the manual: “SpectraView communicates with the display monitors using Display Data Channel - Command Interface (DDC/CI) which is a two-way communications link between the video graphics adapter and display monitor using the normal video signal cable. No extra cables are necessary. All adjustments to the monitor settings are done automatically using this communications link. It is not necessary to manually configure the monitor as all of the necessary settings are made by the software“. Apple has nothing like this, nor can 3rd party software you have to pay for extra do this.
9. SpectraView will bundle a custom mated Colorimeter with their software for calibration, Apple doesn't. The price you pay for software and colorimeter with the SpectraView, depending on what country you live in costs significantly less than buying the hardware and software for a non SpectraView. And that extra money will not provide a fraction of the capabilities outlined.
10. SpectraView PA series offer the ability to calibrate WITHOUT a Colorimeter with the FREE Multiprofiler software since each panel is measured with a very expensive spectroradiometer and that data is embedded in a chip in the panel. It can update the calibration as the unit ages to ensure calibration. Apple has nothing like this.
11. SpectraView can emulate with a single click other behaviors, again on the fly, so it can simulate a non wide gamut display (sRGB) among other standardized behaviors (Broadcast Video DICOM, etc)
12. SpectraView has internal electronic control over contrast ratio, Apple and few others provide this. Real useful for soft proofing on media that has differing contrast ratio's (matt vs. glossy papers).
13. SpectraView has Network support (Windows only). Apple doesn't.
14. SpectraView has provisions to lock the display controls so no accidental alteration to behavior by mistake. Apple doesn't.
15. SpectraView displays allow the user to raise and lower the display for best viewing position AND it can be rotated 90 degrees for Portrait. Apple doesn't provide this.
16. Several SpectraView's support Picture in Picture (you can have two differing calibration's per picture). Apple has nothing like this.
