iPhone 5 64G did not ask me to migrate iPhotos?

The article about how to migrate iPhoto to Photos on iOS8 mentions two things:

1. It will ask you to migrate every time you open iPhoto until you migrate

   "Tap Migrate to start the migration process. If you choose Cancel, the dialog is dismissed, but will again appear the next time you tap the iPhoto icon."

2. It assumes that iPhoto and Photos co-exist.

   "Important: Do not delete iPhoto from your device until after you've successfully migrated your data or it won't be possible to migrate your data."

Here's the problem in two parts:

1. I was never asked to migrate after upgrade to 8, or the other two upgrades finally ending in 8.1
2. There is no longer an iPhoto app on my iPhone to migrate

iPhone information:

• iPhone 5 64GB White & Silver (GSM) Unlocked (MD643C/A)
• iOS: 8.1 (12B411)
• Apple A6, dual core, 1300 MHz

MacBook Pro

OS: Yosemite 10.10

Photo all: iPhoto (not Photos as on my iPhone

iPhoto on my iPhone was entirely replaced by Photos - same icon, some location in my apps organization. It doesn't appear that Photos was added as a separate app. When I look at the apps on my iPhone in the App Store or anywhere under Settings, it doesn't show that iPhoto still exists in the list, as if it had been deleted like other apps. This leads me to believe the Photos entirely replaced iPhoto without asking me to migrate.

Also, all iPhone photos I've taken since upgrading to 8.1 only appear on my MacBook Pro through the Photo Stream. I do not get prompted to add the newer photos at all, even as duplicates, no new events are created. It's still called iPhotos on my Mac, running Yosemite 10.10.

Some apps, like Facebook, also don't recognize these newer photos. The Google+ app does. I know those apps are independent of Apple, but obviously they look at the photos on my iPhone differently.
