The sRGB specification captures the typical behavior of a CRT computer 
display in the mid '90s.  You would be hard-pressed to find an 
uncalibrated computer display which works like that today.

Many modern computer LCD panels do offer an 'sRGB' mode in their setup 
menu.  Computer LCD panels are hardly ever delivered in that mode.

Web content is now often viewed on cell phones, netbooks, and pad 
computers, which may differ even further from sRGB.  If these devices 
displayed in sRGB then they would be passed over by customers and 
would not sell.  Customers always buy the device with the most vibrant 

Good luck. :-)
