IOS 5.1.1 update reduced my iPad 2 screen's brightness by 10-20%

Question

APPLE CPU HARDWARE / GRAPHIC TEAMS:  Once I updated my iPad 2 to the IOS 5.1.1, I *immediately* noticed that my screen's maximum brightness level has been noticeably reduced by approximately 10-15%, possibly even as much 20%, as compared to IOS 5.1
Even my 5 year old daughter immediately noticed the difference the moment she tried watching a movie. "Daddy, how come the screen is darker?".
Of course, this was a battery life call.  And I know the battery may be the single biggest source of pain for most of the hardware teams in IL5 and IL6 (etc).
The good folks in CPU Software who know me, also know of my reputation for freely voicing my opinions (regardless of who it annoys in management), but you all know I don't bother making noise unless it really is a worthy issue. 
WIth the understanding that the screen brightness reduction "fix" was made with very good intentions, it is nonetheless, a BAD CALL.
Please consider fixing it in update 5.1.2., by allowing the user to make the judgement call for screen brightness vs. battery life.
(On a scale of 1 -10)
• Concern over losing a minute amount of battery life (beyond 6 hours life) = 5 (max).
• Concern over losing a noticeable amount of screen brightness = 9.
Please contact me if you need more info.  Thank you very kindly.

I posted here because Apple does monitor these sites (like hawks).
Yes, it is a real and noticeable issue.  It may be specific to my unit's build date though (the battery components used, or screen components).  Apple knows all about it, believe me, and is hoping they won't see posts like this - here - on this user site.
I appologise if this post is perceived as being a misuse of this site, but it was, in fact, quite intentional.
