This is what I've been saying all along (my background goes back to the scanners used in some of the early digital restorations, like Snow White)... everything we are watching on Blu-ray was mastered on displays running 2.2-2.3 gamma (in my experience, I didn't see 2.35 being used, but you've probably seen more mastering setups than I have). This also explains why setting your display to 2.4 or 2.5 NOW will make everything look WAY too dark.
Trying to shift the whole industry to a different gamma now is going to have to be done carefully. The difference between 2.2-2.3 and 2.4 is fairly significant (especially 2.2 vs 2.4). Not everybody is going to change overnight and there will be legacy inventory out there for a LONG LONG LONG time with the "old" gamma encoded on them. There will have to be some kind of "trigger" embedded in newly mastered content that switches compatible video displays to 2.4 (or whatever the final standard is) for that content and allows the display to drop back to 2.2 for legacy content that is not mastered to the new, darker, gamma standard. This switchover could become a real annoyance if there's not some relatively seamless way to accommodate both legacy content and "new" content mastered to 1884 or whatever the "final" standard is -- it will be really annoying if content is always either too bright or too dim because the display gamma and content gamma don't match.
